This study aimed at preparing low cost activated carbon (AC) from sugarcane bagasse by ZnCl2 activation and evaluating the effects of synthesis conditions and variables using the response surface methodology (RSM) approach for the adsorption of Cu (II) ion from aqueous solution by the synthesized ACs. | Journal of Science and Technology 54 (1A) (2016) 277-284 PREPARATION OF ACTIVATED CARBON FROM SUGARCANE BAGASSE USING ZnCl2 FOR THE REMOVAL OF Cu (II) ION FROM AQUEOUS SOLUTION: APPLICATION OF RESPONSE SURFACE METHODOLOGY (RSM) Van Thuan Tran, Bui Thi Phuong Quynh, Thanh Khoa Phung, Giang Ngoc Ha, Thi Thuong Nguyen, Long Giang Bach* NTT Institute of Hi-Technology, Nguyen Tat Thanh University, 300A Nguyen Tat Thanh, District 4, Ho Chi Minh City, Vietnam * Email: blgiangntt@ Received: 31 August 2015; Accepted for publication: 26 October 2015 ABSTRACT This study aimed at preparing low cost activated carbon (AC) from sugarcane bagasse by ZnCl2 activation and evaluating the effects of synthesis conditions and variables using the response surface methodology (RSM) approach for the adsorption of Cu (II) ion from aqueous solution by the synthesized ACs. From the analysis of variance (ANOVA), the most influential factors including activation temperature, impregnation ratio and activation time on each experimental design response were investigated. The optimized conditions for preparation of AC and removal of Cu (II) ions were identified with the activation temperature of 673 K, impregnation ratio of and activation time of minutes. An optimized conditions based– test experiment with % of AC yield and % Cu (II) ion removal was observed. Keywords: sugarcane bagasse, activated carbon; response surface methodology (RSM). 1. INTRODUCTION Copper (II) contamination in groundwater source adversely affects living species, ecological systems as well as psychological health of human. Conventional copper (II) ion elimination processes including chemical precipitation, ion exchange, solvent extraction, ultra filtration, reverse osmosis and membrane filtration exposed some disadvantages such as economically inefficient technique and safe ineligibility [1]. Among well–known adsorbents, AC is much paid attention due to their high adsorption capacity for .
