AB  - Peach stones, a valuable agro-industrial by-product available in many countries worldwide, comprise a renewable resource, which can be widely applied for multifunctional purposes. Its important advantages such as high-energy value, low ash content, low price and wide abundance, make peach stones an ideal fuel for energy production, but also for new materials synthesis. Although peach stones exhibit adequate combustion properties, allowing their direct use with minimal physical/chemical treatment, they often need further modification in order to improve their thermal properties, where slow pyrolysis is frequently used. This study aims to provide a practical and effective solution to the revalorization of waste biomass originating from the fruit processing industry, through slow pyrolysis in order to convert this waste into carbonaceous material - biochar. The thermo-chemical conversion of raw biomass resulted in a stable material with excellent fuel properties, with higher mass energy density and grinding ability, providing biochar with properties, in energy sense, similar or even better than a coal. Biochar has a higher fixed carbon content and a higher energy potential than biomass itself, and its application as a biofuel might reduce emissions of greenhouse gases, as it reduces the amount of waste landed and increases the share of energy generated from renewable sources.

AB  - In this study, slow pyrolysis was employed for the thermochemical conversion of peach stones (PS), lignocellulosic waste (LCW) from food industry, to prepare biochar (PS-B), a new and efficient sorbent for the removal of toxic dye, brilliant green (BG), from aqueous solution. Detailed characteristics of PS and PS-B were analysed using pH suspension, pHPZC, zeta potential, particle size distribution, thermogravimetric method (TG-DTG), scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM–EDX), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). The results revealed that material loss during slow pyrolysis not only altered the chemical structure of the samples, but also induced the volume shrinking phenomenon, resulting in production of a rougher, porous structure with decreased crystallinity. Also, five times less total organic carbon (TOC) release was demonstrated by biochar compared to native material. Comparison of experimental results for BG sorption by PS and PS-B showed that sorption capacity increased after pyrolysis and that sorption kinetic was significantly improved. The BG sorption by both sorbents followed the pseudo-second-order reaction kinetic model, with the intraparticle diffusion model within pores controlling the adsorption rate in PS-B. Isotherm equilibrium modelling revealed that the Sips isotherm provided the best model fit with maximum sorption capacity of 82.53 and 101.11 mg/g for PS and PS-B, respectively. A possible sorption mechanism of BG was achieved through pore filling (porous diffusion), hydrogen bonding, electrostatic attraction and π-π interactions. The results demonstrated that biochar derived from peach stones can be used as a promising green material for removing BG from contaminated waters.

AB  - Anaerobic digestion is a natural process of organic material degradation by different kinds of microorganisms in the absence of oxygen. This process is used for industrial purpose to manage waste streams or to produce biogas. It gives a major contribution in reduction of harmful effects of organic waste disposal to the environment. The aim of agricultural waste pretreatment in biogas production is to decrease the retention time, improve utilization of raw material and improve the overall productivity and energy efficiency of the production process. In this paper the effects of combined chemical and mechanical pretreatment of corn straw biomass on biogas yield during anaerobic digestion of the feedstock were analyzed. The impact of pretreatment and process parameters in biogas production was analyzed by process simulation using the software SuperPro Designer. Using this tool, it was shown that alkaline pretreatment leads to an decrease of degradation time along with an increase in biogas yield.

AB  - In this study the novel biosorbent - raw corn silk (CS) was investigated for Cu2+ and Zn2+ removal from aqueous solutions. The physical and chemical properties of CS were determined by SEM - EDX and ATR - FTIR techniques. The SEM micrographs revealed that surface morphology of CS is suitable for metal adsorption, while FTIR analysis confirmed presence of various active groups (O-H, C-O, C-O C, C=C and amide II) which could interact with metal ions. The adsorption experiments were performed in batch system. Experimental data were fitted by pseudo - first order and pseudo - second order kinetic models as well as Langmuir and Freundlich isotherm models. Biosorption of the both metals follow pseudo second order kinetic model. The best fitting adsorption model is Langmuir model and the maximum biosorption capacities (q(max)) for Cu2+ and Zn2+ at 313 K and pH 5.0 were 15.35 mg g(-1) and 13.98 mg g(-1), respectively. The thermodynamic parameters such as Gibbs free energy change (Delta G), enthalpy change (Delta H) and entropy change (Delta S) were studied at different metal concentration and three temperatures. According to thermodynamic study, the biosorption process for both metals is feasible, endothermic and spontaneous. According to thermodynamic study, the biosorption process for both metals is feasible, endothermic and spontaneous. Ion - exchange is the dominant mechanism in adsorption of Cu2+ and Zn2+ on the CS with a certain degree of complexation. Desorption study was performed in three adsorption/desorption cycles with diluted nitric acid. Results show that after metal adsorption CS can be efficiently recovered and reused for new adsorption process. Obtained results indicated that corn silk could be used as efficient novel biosorbent for Cu2+ and Zn2+ removal from water samples.

AB  - The objective of this study was to investigate corncob as biosorbent for heavy metals removal from aqueous solutions. All biosorption experiments were performed in batch system. The biosorbent were caracterized by thermal analysis (DTA/TGA), Scanning Electron Microscopy and Energy Disperzive X-Ray analysis (SEM-EDX) and Fourier Transform Infrared Spectroscopy (FTIR) analysis. FTIR analysis of corn cob before and after Pb2+, Cu2+ and Zn2+ removal from aqueous solutions showed that ion exchange and chemisorption were involved in biosorption process of metal ions on to corn cob. Experimental data were fitted by Langmuir and Freundlich isotherm models. Maximum adsorption capacity of corn cob for Pb2+, Cu2+ and Zn2+ were 5,59; 2,62 i 1,23 mg/g, respectively. Desorption study showed that metal adsorbed corn cob can be effectively regenerated by HNO3 solution. Results from this study indicated that corn cob can be used as potential biosorbent for Pb2+, Cu2+ and Zn2+ removal from aqueous solutions.

Rezultati ovog istraživanja ukazuju da se oklasak kukuruza može primeniti kao potencijalni biosorbent za uklanjanje Pb2+, Cu2+ i Zn2+ jona iz vodenih rastvora.",

AB  - Aquatic weed Myriophyllum spicatum L. is one of the most invasive water plants known. In many countries, it is usually harvested and landfilled, where aerobic and anaerobic decomposition takes place. In this research, the kinetic, equilibrium, and desorption studies of biosorption of Pb(II), Cu(II), Cd(II), Ni(II), and Zn(II) ions onto compost of M. spicatum were investigated in batch experiments. Biosorbent was characterized by scaning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). SEM analysis showed that ion exchange between divalent cations Ca(II) and selected metals takes place. The results of FTIR exposed that carbonyl, carboxyl, hydroxyl, and phenyl groups are main binding sites for those heavy metal ions. The rate of adsorption of the five heavy metals was fast, which achieved equilibrium in 40 min, and followed the pseudo-second-order model well. Langmuir, Freundlich, and Sips equilibrium adsorption models were studied, and Sips isotherm gave the best fit for experimental data. Desorption by 0.1 M HNO3 did not fully recover the metals sorbed onto the compost, indicating that reusing this material as biosorbent is not possible. Furthermore, the use of spent biosorbent as a soil fertilizer is proposed.

AB  - BACKGROUND Lead is one of the frequent contaminants of industrial wastewater. Since it has been shown that aquatic plants can be used for the removal of heavy metals, herein Pb(II) biosorption by Myriophyllum spicatum and its compost were investigated. Effects of pH, ionic strength and contact time were analyzed using a batch experiment. Biomasses were characterized chemically and by Fourier transform infrared spectroscopy, scanning electron microscopy and X-ray diffraction techniques. RESULTS The adsorption process of both biosorbents followed a pseudo-second-order kinetic model. Compost exhibits better Pb(II) removal from solution (71%) compared with the plant (61%). Lead binding capacities for M. spicatum and its compost were 0.234 mmol g(-1) and 0.287 mmol g(-1) at pH 5.0, respectively. Lead binding takes place mainly through an ion exchange mechanism, but chemisorption via identified functional groups cannot be neglected. The Langmuir, Freundlich and Sips adsorption models for compost were applied. The Sips isotherm model gave the best fit with the equilibrium experimental data. The sorption process by compost was endothermic and spontaneous. CONCLUSION Aquatic weed compost as a low cost biosorbent with high biosorption capacity can potentially be used for the removal of lead from wastewaters.
