Bagasse fly ash, a waste material generated in the sugar industry, collected from a local sugar firm at Kom‐Umbo district (42 km to the north of the midcity of Aswan), Aswan Governorate, Egypt, was used as a low cost and effective adsorbing surface for the removal of Cu 2+ , Ni 2+ , Zn 2+ , and Cr 3+ from industrial waste water. The adsorption capacity was followed as a function of pH, adsorbent dose, metal ion concentration, shaking time, and divers ions. Under the optimum conditions used, more than 95% of some of the ions under study were successfully removed. The data were fitted using both Freundlich and Langmuir isotherms.
