Abstract
Black pepper (Piper nigrum) had been used since ancient time as spice and medicines. However, the production of pepper produce large amount of waste. Activated carbon produced from P. nigrum was used as an adsorbent for heavy metals (Ni, Cu and Cd) removal. The activated carbon was chemically activated using sulphuric acid, H2SO4. The metals concentration before and after adsorption was determined using Flame Atomic Absorption Spectrometer (FAAS). The surface characterization of the activated carbon was performed using Scanni ng Electron Microscope (SEM). Adsorption study revealed that P. nigrum activated carbon is dependent on the adsorbent dosage, concentration and time. The optimum adsorbent dosage, concentration and agitation time were found to be 1 g, 10 mg/L and 20 minutes, respectively. Results obtained also indicated that P. nigrum activated carbon has a potential as an adsorbent for removal of Ni, Cu and Cd even though its removal efficiency is lower than commercial activated carbon.
