Copper is one of the most important heavy metal used in various industries. Nevertheless, it is one of the main pollutants in the environmental. As it poses toxicity to an ecosystem, it is a matter of concern. Hence we attempt to conduct adsorption studies to remove the copper from a synthetic media. Coconut husk and rice husk were deployed and their efficiency as adsorbent was studied. The experiments were investigated by adopting Response Surface Methodology (RSM) using BoxBehnken Design. The influences of physical and chemical parameters (initial adsorbate concentration, adsorbent dosage and contact time) were studied. As predicated by the model, a maximum of 82.4% and 94.7% were adsorbed by rice husk and coconut husk respectively. The regression co-efficient of 87.5% and 97.6% were displayed by rice husk and coconut husk. The results infer that coconut husk could be a choice as an adsorbent over a rice husk.
