چکیده

Представлены результаты исследования адсорбционных свойств сшитых эпихлоргидрином хитозановых сфер. В ходе была разработана методика получения и сшивки сфер, а также магнитно-разделяемых композитов на их основе. Адсорбционная способность сфер исследована примере водных растворов NiCl2 K2Cr2O7 при варьировании концентрации ионов Ni2+ Cr2О7 2- . Было показано, что адсорбционное равновесие в случае хлорида никеля достигалось за 60 мин, тогда как бихромата калия требовалось более продолжительное время (420 мин более). The paper presents the results of a study adsorption properties epichlorohydrin-cross-linked chitosan spheres. During study, procedure was developed for obtaining and cross-linking spheres, as well chitosan-based magnetically separable composites. capacity cross-linked spheres tested by example aqueous solutions Cr2O7 with different concentrations. It shown that equilibrium in case achieved min, whereas longer time required min or more).

Effect of Eggshell on Mechanical Properties of Epichlorohydrin Cross-linked Chitosan/Eggshell Composites

The effect of eggshell particles on the mechanical properties of epichlorohydrin crosslinked chitosan/eggshell composites had been studied. The content of eggshell particles in each composites was varied from 2.5 to 13.4% (w/w). The tensile strength was 60% improved, compared to the control chitosan. The composite with 13.4% (w/w) content of eggshell particles showed the optimum tensile strengt...

Wastewater Treatment with Chitosan Nano-particles

Chitosan interact with polyphosphate ions to form nanoparticles with different diameters depending on the mutual ratio among them. Three nanoparticles have been prepared and were characterized by spectral and X-ray diffraction tools. TEM analysis revealed there diameters. The nanoparticles were thoroughly studied for wastewater treatment such as the removal of Total Suspended Solid (TSS), Bioch...

Biosorption of Cu(II), Zn(II), Ni(II) and Pb(II) ions by cross-linked metal-imprinted chitosans with epichlorohydrin.

Cross-linked metal-imprinted chitosan microparticles were prepared from chitosan, using four metals (Cu(II), Zn(II), Ni(II), and Pb(II)) as templates, and epichlorohydrin as the cross-linker. The microparticles were characterized by Fourier transform infrared spectroscopy, solid state (13)C nuclear magnetic resonance spectroscopy, and energy-dispersive X-ray spectroscopy. They were used for com...

Chitosan/Polyethersulfone Composite Nanofiltration Membrane for Industrial Wastewater Treatment

Chitosan/polyethersulfone (CS/PES) composite membrane was prepared from casting chitosan solution on polyethersulfone substrate membrane. The Substrate membrane was prepared by phase inversion technique using polyethersulfone (PES) and dimethylacetamide (DMAc) as solvent with and without the addition of polyvinylpyrrolidone (PVP) as pore-forming agent. The effects of the composition of the c...
