| dc.description.abstract | Activated carbon is largely used as an adsorbent with so many applications including water treatment. The aim of this study is to investigate the influence of various variables such as carbonization time, carbonization temperature and heating rate on the percentage removal and the amount of adsorption at equilibrium for Arsenic. The activated carbon was prepared using physiochemical method where KOH being used as an activating agent. The range of carbonization temperature used are between 417 ˚C to 433 ˚C, carbonization time between 31 min to 43 min while for the heating rate are between 2.5 ˚C/min to 12.5 ˚C/min. Batch adsorption test was conducted to evaluate the performance of activated carbon produced based on its removal percentage and amount of Arsenic adsorption. The best activated carbon produced at the medium level condition which was 37.5 minutes carbonization time at 425 ˚C with 7.5˚C/min heating rate where it gives the highest removal percentage about 45.55% and 5.389 mg/g adsorption amount. The most significant factors that influence the adsorption performance of the activated carbon is the heating rate as the variables have a significant interaction with the other two variables. The characterization analysis have been made to the prepared activated carbon to determine the porosity distribution with its profile. In summary, it | en_US |
