Batch.Adsorption experiment was conducted to examine the effects of dosage adsorbent, time contact, and pH 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.
