Abstract
Copper II sulphate is one of those contaminants that undermine the economic, environment and deleterious health effects on people. Kaolin sample from Illela local government of Sokoto state, Nigeria was used as adsorbent for removal of Copper II sulphate and to check for the effect of concentration. The collected kaolin sample was pretreated to remove debris, grinded and dried. The adsorption methods of the parameters onto the kaolin were investigated by maintaining constant amount of adsorbent, temperature and other factors except for concentration. The results from different concentrations shows that with increase in concentration of the copper solution, the more the kaolin adsorbed. From the findings, it was established that kaolin form Illela local government of Sokoto state, Nigeria can serve as an economic, safe and effective natural adsorbent for removal of copper II sulphate from wastewater.
