AB  - Styrene-butadiene (SBR) and acrylonitrile-butadiene (NBR) rubber blends with tetramethyl thiuram disulfide (TMTD) and tetramethyl thiuram monosulfide (TMTS) accelerators and environmentally friendly plasticizers, obtained from PET recycling and biobased resources (LA/PG/PET/EG/LA), were prepared. The mechanical properties of the obtained rubber products were tested and compared with those of commercial dioctyl terephthalate (DOTP). TMTS was prepared by simple and efficient one-pot synthesis from dimethylamine, carbon disulfide, potassium cyanide, and ammonium chloride as catalysts in recycled isopropanol/water azeotrope as solvent. In a comparative study, methoxide, ethoxide, iodide, and amide ions were also used. The two-step reaction mechanism of TMTS synthesis involves the oxidation of the amine salt of dimethyldithiocarbamic acid to TMTD by hydrogen peroxide and sulfur elimination from the TMTD disulfide bond. Potassium cyanide appears to be the most efficient nucleophile. The simplicity of operation, mild reaction conditions, solvent recycling, high yields, and applicability to the industrial level are the advantages of this process. Shore hardness, tensile strength, and compression test results of vulcanized blends before and after aging showed similar properties for both accelerators, while somewhat better results were obtained with LA/PG/PET/EG/LA plasticizer.

AB  - Oxidized cotton linters, TOCell, were used as an adsorbent or derived membrane there from by linters
cross-linking with citric acid. The adsorption/desorption study of Pb2+, methylene blue (MB), and crystal
violet (CV) removal, was performed. Adsorption data fitting, obtained using the Langmuir model, gave
116 mg g 1 (Pb2+), 179 mg g 1 (MB) and 482 mg g 1 (CV) at 25 ℃ for TOCell linters, while 101 mg g 1
(Pb2+), 165 mg g 1 (MB) and 426 mg g 1 (CV) for TOCell membrane. After desorption dyes were subjected
to photocatalytic degradation while lead was transformed into stable lead phthalate (LP), and further
used as filler in composites based on unsaturated polyester resins (UPR). UPR was synthesized from
waste polyethylene terephthalate (PET). Structural characterization was performed using FTIR, SEM,
and NMR methods. Composites loaded with acryloyl modified kraft lignin (A-KfL) and/or LP was tested
for tensile strength, Vickers microhardness, and fire resistance (UL-94 V method). The best mechanical
and fireproofing properties were obtained at 15 wt.% A-KfL and 40 wt.% Al(OH)3 addition. The results
of the toxicity leaching test (TCLP) confirmed the environmentally safe stabilization of desorbed pollutant
in the UPR matrix. Application of environmentally friendly membranes, susceptible to easy biodegradation, had low negative effects to the environment.

AB  - The morphological properties and adsorption potential of lignin-based porous
microspheres (LgMS) for heavy metals ions were investigated. LgMS were produced via
suspension copolymerization of unmodified or acryloyl modified kraft lignin with amine
(polyethylene imine - PEI) or acrylate (trimethylolpropanetriacrylate - TMPTA) functional
polymers. Structural and morphological characterization of LgMS was performed using
FTIR, BET, and SEM techniques. Copolymerization of the unmodified lignin and PEI, using
epoxy chloropropane cross-linker, provided highly porous LgMS, with 800 ± 80 μm
diameter, 7.68 m2g−1 surface area and 7.7 mmol g−1 of terminal amino groups. The LgMS
produced by copolymerization of the acryloyl functionalized lignin and TMPTA provided a
decrease in LgMS diameter (253 ± 42 μm), while surface area and porosity increase, 69.4 m2
g-1and 59%, respectively. The effect of acryloyl functionalization of kraft lignin on the
LgMS adsorption capacity for Ni2+ ions was also studied in a comparative study. The results
showed that final adsorption performances of LgMS were affected by the key factors
including lignin functionality and the LgMS synthesis condition. Lower adsorption capacity
of 22.6 mg g-1 for Ni2+ was observed for acryloyl LgMS due to lower affinity for formation
electrostatic interactions of Ni2+ ions with phenol/hydroxyl groups responsible for
adsorption. Opposite was found for amino LgMS where 49.4 mg g-1was achieved. However,
this study indicated that removal of heavy metal ions from wastewater can be realized
through the application of eco-friendly lignin-based porous microspheres.

AB  - In this paper, the capillary rise and sorption ability of hemp fibers oxidized with hydrogen peroxide and potassium permanganate were studied, with the aim to get more insight into the changes in the structure of hemp fibers caused by oxidation, and to compare the influence of applied oxidative agents on hemp fibers. Capillary rise was presented as a function of a liquid rise height vs times, with determined all three capillary coefficients, while sorption ability was determined as water retention values and moisture sorption. For structural analysis of the samples the ATR-FTIR technique was used. Also, the amount of aldehyde and carboxyl groups and the lignin content in oxidized fibers were determined. The surface fibers morphology was observed by FESEM. In all oxidized hemp fibers an increase in capillarity was obtained for both oxidizing agents (33-75 mm for H2O2, and 40-114 mm for KMnO4), compared to 31 mm for unmodified fibers, but decreased sorption ability. Application of both oxidative agents, were successful for introduction of functional groups into oxidized fibers, for reduction of the amount of non-cellulosic substances, as well as moisture sorption. Simultaneously, the fibers became finer, cleaner, whiter, softer and more suitable for further processing, while, generally, higher influence on changes into oxidized hemp fibers was achieved by oxidation with KMnO4, compared to oxidation with H2O2.

abstract = "In this paper, the capillary rise and sorption ability of hemp fibers oxidized with hydrogen peroxide and potassium permanganate were studied, with the aim to get more insight into the changes in the structure of hemp fibers caused by oxidation, and to compare the influence of applied oxidative agents on hemp fibers. Capillary rise was presented as a function of a liquid rise height vs times, with determined all three capillary coefficients, while sorption ability was determined as water retention values and moisture sorption. For structural analysis of the samples the ATR-FTIR technique was used. Also, the amount of aldehyde and carboxyl groups and the lignin content in oxidized fibers were determined. The surface fibers morphology was observed by FESEM. In all oxidized hemp fibers an increase in capillarity was obtained for both oxidizing agents (33-75 mm for H2O2, and 40-114 mm for KMnO4), compared to 31 mm for unmodified fibers, but decreased sorption ability. Application of both oxidative agents, were successful for introduction of functional groups into oxidized fibers, for reduction of the amount of non-cellulosic substances, as well as moisture sorption. Simultaneously, the fibers became finer, cleaner, whiter, softer and more suitable for further processing, while, generally, higher influence on changes into oxidized hemp fibers was achieved by oxidation with KMnO4, compared to oxidation with H2O2.",

AB  - Applications of hemp fibers, as a promising natural material in the textile field, mostly require improved fiber properties. In this paper, the oxidation of hemp fibers with potassium permanganate was applied to reduce the amount of noncellulosic substances and moisture sorption; to introduce functional groups and increase capillarity; make fibers finer, softer and suitable for application in sport wears. The changes in sorption properties were characterized by capillary rise measurement and the ability of water retention and moisture sorption, while changes in mechanical properties were estimated by determination of tenacity and elongation of modified hemp fibers in comparison to the appropriate characteristic of unmodified fibers. ATR-FTIR, SEM techniques, and zeta potential measurement were used for the characterization of fiber structure, morphological and electrokinetic properties. We obtained a finer fiber with increased capillarity (up to 3.68 times) but reduced moisture sorption (down to 1.5 times) and water retention capacity (down to 2.8 times), with accomplished satisfactory preservation of mechanical properties. Obtained oxidized hemp fibers with attained features present a very suitable material for sportswear production. Additionally, in this paper, an improvement of the capillary rise measurement is given.

AB  - Two optimized methods, based on epoxy-amino reactivity of the Cellulose fibres (Cell) modified with diethylenetriamine (Cell-DETA), (3-Glycidyloxypropyl)trimethoxysilane (Cell-Glymo), Lignin modified with epichlorohydrine (EL) and Tannic acid (TA), as an additional crosslinker, were developed for the production of the bio-renewable Cell-EL and Cell-EL-TA membranes. The influences of pH, contact time, adsorbent dose, and temperature on adsorption performances were studied by batch adsorption tests. The calculated capacities: 53.9, 99.9, 97.8 and 63.5, 115.8, 127.5 mg g(-1) for Ni2+, Pb2+, Cr(VI) using Cell-EL and Cell-EL-TA, respectively, were obtained from Langmuir model fitting at 25 degrees C. The thermodynamic parameters indicated spontaneous and low endothermic processes. The results of the kinetic study, i.e. pseudo-second-order (PSO) and Weber-Morris (W-M), suggest an intra-particle diffusion as a rate-limiting step. The semi-empirical quantum chemical calculations aided the analysis of the non-specificand specific adsorbent/adsorbate interactions and their contribution to the overall bonding mechanism. Membrane utility was confirmed by performing a bed column study. In general, three main environmental issues of the present study, biodegradability of the used membrane, desorption efficiency, and development of the technology for the effective effluent water treatment and safe disposal of by-products highly conform to the demand of integrated environmental management system applicability in practice.
