Activated carbon produced from coconut shell (ACS) was used as adsorbent to remove Cu2+, Fe2+, Zn2+ and Pb2+ ions from
electroplating industrial wastewater. The activated carbon produced was chemically activated with zinc chloride. Batch
adsorption experiment was conducted to examine the effects of adsorbent dosage, contact time, pH and stirring rate on
adsorption of Cu2+, Fe2+, Zn2+ and Pb2+ from the wastewater. The obtained results showed that, the adsorption of the metal
ions was adsorbent dosage, contact time, pH and stirring rate dependent. The optimum adsorbent dosage, stirring rate and
pH, were found to be at 1 g, 350 rpm and pH 6 respectively. Kinetic studies showed that pseudo-second-order reaction model
best described the adsorption process. The study also showed that activated carbon prepared from coconut shell can be
efficiently used as low cost alternative for removal of metal ions.
