dc.description.abstractIn this study, the activator used to activate the avocado seed powder was HCl with variation concentration of 2.5, 5.0, and 7.5%. The result of characterization indicated that the powder avocado seed which activated by HCl 5.0% has the best result with water content, ash content, adsorption of iodine, and surface area were 12.28%, 0.02%, 823.71 mg/g, and 86.94 m2/g, respectively. The result of adsorption cadmium (II) and lead (II) ion on avocado seed powder which has been activated showed that efficiency adsorption were 89.05 and 96.81%, respectively. The result of capacity adsorption were 1.12 and 2.34 mg/g, respectively. The result of efficiency and capacity adsorption were effected by functional group of OH, CH, C=C, C–O and C–N which analyzed by Spectrofhotometer Fourier Transform Infrared (FTIR).en_US
