Heavy metals from the electroplating wastewater might cause environmental pollution if not well treated. Generally, carbon adsorption might be used for the final step for further trace metals removal. This study investigated the heavy metal Cu adsorption in the fixed bed column with 1, 10 and 100 mg/L influent concentration. Results showed that K AB decreased as influent Cu concentration increased from 1 to 100 mg/L while N 0 increased as influent concentration increased from 1 to 100 mg/L as can be found in Adams-Bohart model. R 2 was found between 0.8579 and 0.9182. In Thomas model. K TH and q 0 showed the similar trend as K AB and N 0 in the Adams-Bohart model. K TH decreased as influent Cu concentration increased from 1 to 100 mg/L. q 0 increased as influent Cu concentration increased from 1 to 100 mg/L. R 2 of regression model was found between 0.9065 and 0.9836. In Yoon-Nelson model. K YN increased as influent Cu concentration increased from 1 to 100 mg/L while τ decreased as influent Cu concentration increased from 1 to 100 mg/L. Results showed that the three models of Adams-Bohart model, Thmoas model and The Yoon-Nelson model were suitable for the description of Cu adsorption by activated carbon.
