摘要: Abstract In the present study, a cellulose based adsorbent, P(MB-IA)-g-MNCC was synthesized by graft co-polymerization of itaconic acid onto MNCC using EGDMA as crosslinking agent and K 2 S O 8 free radical initiator. characterized FTIR, XRD, SEM, TG VSM. Cd(II) adsorption occurs maximum at pH 6.0. Kinetic isotherm data were described pseudo-second-order kinetic model Sips model, respectively. Adsorbent dosage 2.0 g/L sufficient for complete removal ions from aqueous solutions. The capacity found to be 262.27 mg/g. Spent adsorbent effectively regenerated 0.1 M HCl.
