Abstract :
In this study, medium molecular weight chitosan (CTS) was grafted using a mixture of monomers, itaconic acid (IA) and methacrylamide (MAm) in the presence of the radical initiator, 4, 4-azobis-4-cyanovaleric acid (ACV) and ethylene glycol dimethacrylate (EGDMA) as crosslinker. The optimal grafted product was obtained by gravimetric method (EGDMA = 2 ml, ACV = 0.01 g, IA = 0.01g, MAm = 0.09 g, t = 45min, CTS = 0.2 g). The effective parameters on the adsorption of phenol were investigated by the copolymer and the appropriate pH was determined to be 3.0 - time 45 minutes - absorbent 0.01 g - absorbate 350 mg/L, qmax 693 mg/g. The characterization was performed by FTIR and SEM methods.
