Abstract
In the present study, cellulose carbon encapsulated zinc oxide (CCZnO) was synthesized by the charring of cellulose acetate onto ZnO particles. CCZnO was characterized by SEM, FTIR, XRD, TGA, and DTA. The adsorption feature of CCZnO was studied for the removal of toxic amaranth dye and 99% adsorption of amaranth was observed under the sonication condition. Maximum desorption (98.5%) was observed with the 0.1 M NaOH at 50°C. FTIR spectra revealed that N˭N, O‒H and S‒O were the main groups which participate in the dye binding on the CCZnO surface.
