Modification of Cellulose with 4.4 Diaminodiphenylether-O-Hydroxibenzaldehide as Adsorbent and Its Application for Adsorbing Metalic Ion of Cd2+ In Aqueous Solution

Abstract

This research on the modification of cellulose using 4,4-diaminodiphenylether and o-hydroxybenzaldehyde and its application to adsorb Cd 2+ in aqueous solution has been done. The adsorption studies of cellulose and modified cellulose were done by using batch technique. The cellulose and modified cellulose were characterized by FTIR. The FTIR spectra revealed characteristic bands of 1573 cm . Kapasitas adsorpsi dan energi adsorpsi ion Cd 2+ terhadap selulosa adalah 71.43 mg/g dan 4.14 kJ/mol. Sedangkan selulosa termodifikasi menghasilkan kapasitas dan energi adsorpsi sebesar 55.56 mg/g dan 0.13 kJ/mol.
