Abstract: The main objective of this study was to remove heavy metals such as Cu, Co, Zn, Pb, As, Cd and Cr from industrial wastewater by adsorption using local bentonite clay and roasted date pits. The concentration level of various heavy metals in the industrial wastewater of Riyadh City was above the permissible recommended limits. The minimum removal efficiency of the adsorption of metal ions on bentonite clay and roasted date pits was 97%. Also, the concentration level of hazardous heavy metals in the treated water was within the permissible limits for crop production. The study showed good potential for removing heavy metal ions from industrial wastewater by adsorption using local bentonite clay and roasted date pits.
