Chitosan nanoparticle hydrogel based sebacoyl moiety with remarkable capability for metal ion removal from aqueous systems.

Abstract:

:In this present study, a new modified chitosan hydrogel, Cts-SC NPs, was prepared from a one pot reaction of sebacoyl chloride (SC) with chitosan in the presence of 1% v/v glacial acetic acid and 1% w/v sodium tripolyphosphate (TPP) using an ionotropic gelation technique. The modified chitosan hydrogel, Cts-SC NPs, was characterized by FTIR, TEM, XRD, TGA, DSC and SEM. The adsorption efficiency of Cts-SC NPs for metal ions Hg2+, Ni2+ and Co2+ from aqueous solution was evaluated. The effects of various parameters such as contact time, pH and initial metal ions concentration were investigated. Adsorption isotherm data were fitted using different two-parameter models. Modified chitosan hydrogel Cts-SC NPs had remarkable adsorption of Hg2+, Ni2+ and Co2+ ions than chitosan hydrogel Cts-NPs. The antimicrobial activity of Cts-NPs towards the bacteria, Bacillus subtilis, Pseudomonas aeruginosa and fungus Aspergillus flavus was improved by modification with sebacoyl chloride to give Cts-SC NPs.
