However, activated carbon is costly and the efficiency of dye removal in single-stage adsorber is highly doubtful due to the time limitation. Thus, alternative adsorbents and the possibility of greater efficiency by two-stage adsorber have been investigated. It is well-known that the waste materials from agricultural activities is obtainable and provide a low-cost adsorbent. Whereas two-stage adsorber is known to be more beneficiary than single-stage because mass and contact time between adsorbent and adsorbate is optimized. In this study, commercialized coconut shell-based activated carbon is used to remove Malachite Green in two-stage batch adsorber system. The key characteristics for the activated carbon include 118.74 m2/g SBET area, 0.53 cm3/g total volume, 0.13cm3/g mesopore volume and 1.89nm diameter. The uptake capacity and adsorption affinity has been determined at 70.8mg/g and 44.5mg/g respectively. In this research, malachite green dye solution of 100 mL volume is used to reduce the initial concentration of dye from 50 mg/L to 1.314 mg/L in a two-stage batch adsorption system. A detailed evaluation is made on the benefits of utilizing two-stage system over a single-stage which a decrease in total minimum adsorbent mass from 0.1g in single-stage to 0.078g in two-stage and in total contact time from 360 minutes in single-stage to 1.43 minutes in two-stage batch adsorption system. fahmimoksen UTM 65 p.
