Abstract
A study on the performance of a renewable activated carbon towards concentration reduction for ethyl orange dye was conducted. The coconut shell activated carbon was prepared by varying the carbonization temperature and impregnation ratio of chemical activation agent and coconut shell. The effect of adsorbent dosage and temperature on performance of the synthesized AC was determined. The finding showed that the impregnation ratio of 2 and carbonization temperature of 800 ˚C were the best condition to synthesis the activated carbon. The result also showed that the increment in adsorbent dosage increased the sorption capacity for coconut shell AC. However, the temperature changes caused the fluctuation in reduction of dye concentration. Comparison with commercial activated carbon indicated that coconut shell AC had proved to be a low cost and efficient adsorbent in this research.
