Influence of hemicelluloses and lignin content on structure and sorption properties of flax fibers (Linum usitatissimum L.)
(Springer, Dordrecht, 2018)
In this work, alkali and oxidative treatments were employed to obtain flax fibers with different content of hemicelluloses and lignin, in order to study the influence of chemical composition on structure and sorption ...
Study of interaction between nitrogen DBD plasma-treated viscose fibers and divalent ions Ca2+ and Cu2+
(Springer, Dordrecht, 2014)
Viscose fibers were treated with atmospheric pressure dielectric barrier discharge (DBD) plasma obtained in nitrogen in order to activate the fiber surface prior to sorption of the divalent ions Ca2+ and Cu2+. Methylene ...
Iron-Modified Sepiolite for Ni2+ Sorption from Aqueous Solution: An Equilibrium, Kinetic, and Thermodynamic Study
(Amer Chemical Soc, Washington, 2010)
Sepiolite was used for the synthesis of the sepiolite-iron oxide system to obtain a sorbent suitable for the removal of Ni2+ from aqueous solution. The modified material, Fe-sepiolite, was characterized by X-ray diffraction ...
Bioreactor Studies of Alginate Hydrogels for Potential Applications in Biomedicine
(Elsevier Science Bv, Amsterdam, 2010)
Influence of periodate oxidation on sorption properties of viscose yarn
(Editura Acad Romane, Bucuresti, 2018)
Viscose yarn was submitted to oxidation using different sodium periodate concentrations for various periods of time in order to investigate the influence of oxidation on the chemical and sorption properties of the resulting ...
Silver incorporation on viscose and cotton fibers after air, nitrogen and oxygen DBD plasma pretreatment
(Springer, Dordrecht, 2013)
Dielectric barrier discharge (DBD) pretreatments in air, nitrogen and oxygen plasma of viscose and cotton fabrics with subsequent immobilization of silver were studied. Surface activation of treated fibers was evaluated ...
Re-refining of waste mineral insulating oil by extraction with N-methyl-2-pyrrolidone
(Elsevier Science Bv, Amsterdam, 2006)
Extraction with N-methyl-2-pyrrolidone (NMP) via the three-stage mixer-settler operation was studied as possible process for re-refining of waste mineral insulating oil. The following extraction process parameters were ...
A comparative study of chromatographic lipophilicity and bioactivity parameters of selected spirohydantoins
(Taylor & Francis Inc, Philadelphia, 2020)
In this study, lipophilicity of 21 cycloalkylspiro-5-hidantoins was assessed. The overall goal of lipophilicity evaluation is preliminary investigation which should result in a decrease of the traditionally high attrition ...
Multipurpose nonwoven viscose/polypropylene fabrics: Effect of fabric characteristics on sorption and dielectric properties
(Wiley, Hoboken, 2018)
In this work, sorption and dielectric properties of viscose/polypropylene multipurpose nonwoven fabrics were examined. The analysis of sorption behavior showed that the changes of the water absorptive capacity, the height ...
Supercritical and ultrasound-assisted extracts fromPleurotus pulmonariusmushroom: chemical profiles, antioxidative, and enzyme-inhibitory properties
(Wiley, Hoboken, 2021)
Background This study provides an insight into the impact of ultrasound-assisted extraction with water as solvent (UAEW) and extraction by supercritical carbon dioxide (SC-CO2) with 5% EtOH on antioxidant and enzyme ...
