【 摘 要 】

Activated carbon powder was obtained by treating coconut fibre with ammonium chloride and carbonized at 400oC. The powdered activated carbon was sieved. The portion that passed through a 212 um and retained on a 90 um mesh size was used for this study. The treatment was done to increase the surface area and the adsorption site of the carbon. The activated carbon was characterized in terms of pH, surface area, loss on ignition, moisture content and bulk density. The adsorption pattern of soluble petroleum fraction (kerosene and diesel) on coconut fibre carbons as a function of time was studied. The removal of diesel and kerosene from aqueous solutions measured by changes in the chemical oxygen demand shows that removal efficiency was less than 45% corresponding to about 6.8 mg/l/g decreases in chemical oxygen demand (COD). The removal of diesel and kerosene from aqueous solution followed a psuedo first order rate law.
