New insight into the role of crosslinkers and composition on selectivity and kinetics of antimony uptake by chitosan-titania composite beads

Abstract Role of composition and the nature crosslinking on properties titania-chitosan beads have been investigated in detail. The investigations were done order to explore feasibility design synthesis with bespoke functionality based intended application. This would greatly enhance potential for industrial application these biopolymer beads. Beads varying compositions (of titania chitosan) prepared crosslinked using epichlorohydrin or glutaraldehyde. physical characteristics antimony binding resultant Influence chitosan amount swelling was seen be more predominant glutaraldehyde (TA-Cts-Glu). TA-Cts-Glu showed better (Sb(III) Sb(V)) uptake as compared (TA-CTS-Epi). While faster kinetics TA-CTS-Epi beads, latter selectivity towards Sb(III) against transition metal cations. Further, exhibited differential Sb(V) Sb(III). equal amounts maximum while TA-Cts-Epi higher ratio least. enhanced by chitosan, aided predominantly content
