Alginate and algal-biomass (Laminaria digitata) beads were prepared by homogeneous Ca ionotropic gelation. In addition, glutaraldehyde-crosslinked poly (ethyleneimine) (PEI) was incorporated into algal beads. The three sorbents characterized scanning electron microscopy (SEM) coupled with energy dispersive X-ray analysis (EDX): the sorption occurs in whole mass of sorbents. Sorption experiments conducted to evaluate impact pH, isotherms, uptake kinetics. A special attention paid effect...
A new magnetic functionalized derivative of chitosan is synthesized and characterized for the sorption metal ions (environmental applications valorization). The chemical modification glycine consists of: activation support with epichlorohydrin, followed by reaction either to produce reference material (i.e., Gly sorbent) or ester hydrochloride, hydrazinolysis synthesize hydrazide sorbent HGly sorbent). materials are titration, elemental analysis, FTIR analysis (Fourrier-transform infrared...
Two kinds of algal beads were prepared using a carrageenan-based alga (Chrondrus crispus) and an alginate-based (Laminara digitata) ionotropically gelled with K(I) Ca(II), respectively: the process consists biopolymer partial extraction followed by hydrogel formation. The modified branched polyethylenimine (bPEI) glutaraldehyde (GA) impregnation method to improve their sorption capacity for Pd(II) in acid solution. SEM-EDX FTIR techniques used characterizing beads. impacts pH presence...
The incorporation of brown algae into biopolymer beads or foams for metal sorption has been previously reported. However, the direct use these biomasses preparing is a new approach. In this study, two kinds porous were prepared by ionotropic gelation using algal biomass (AB, Laminaria digitata) alginate (as reference) and applied Pb(II) sorption. These (manufactured as macroporous discs) packed in filtration holders (simulating fixed-bed column) system was operated either recirculation...
The objectives of this study were to investigate the competitive sorption behaviors and mechanisms heavy metals onto ELMB, a novel eucalyptus-leaf-based magnetic biosorbent, potential application ELMB in treatment actual zinc smelting effluent after necessary pretreatment process. ELMB-metals systems characterized using several techniques. Competitive Zn2+ with Pb2+, Cu2+ Cd2+ was studied by batch experiments used sorbent separated under field. results show that can be considered as...
Abstract The recovery of platinum from industrial waste is critical importance. Usually, the method to dissolve solid with acid form a solution where mainly exists in Pt(IV). Therefor, it urgen efficiently and selectively adsorb Pt(IV) ions leachates. In this study, highly efficient adsorbent was developed by grafting carboxyl amine groups onto melamine sponge alginate-Ca polyethylenimine-glutaraldehyde (ML/ACPG). Combination SEM, FTIR XPS showed that ML/ACPG had tree structure amino,...
