The electroplating industry is one of the most important industries, which use, copper and ,nickel, in batch for ,plating,. However, the electroplating effluent produces ,wastewater containing, several heavy metal ions, which would toxify the water body and be harmful to human beings. Thus, heavy metal removal has become a serious problem to be solved.
