Abstract

This study investigates the influence of wet chemical oxidation using nitric acid and ammonium persulfate on the surface nature and the adsorption properties of activated carbon prepared from sulfuric acid activation of locally Atropa belladonna plant at 200oC. The surface properties of produced carbons (AC-S, AC-S/N and AC-S/A, respectively) were demonstrated by FTIR, potentiometric titration and N2 adsorption. The adsorption properties of these carbons were estimated using methyl green (MG) dye as a cationic dye. The effect of variables including pH, initial  dye concentration and contact time on the adsorption properties of these carbons was studied. Acidic carbon adsorbents were obtained with large content of acidic surface functional groups in the sequence order AC-S
