Selective removal of heavy metals such as Cu, Ni, Co, Mn, Cd, and Pb from tap water that contains relatively high concentrations of calcium and magnesium was carried out with a cation-exchange resin possessing a chelating iminodiacetic acid group. When the concentration of each of these metals in tap water was of the order of a few ppm, their leakage fell below the permitted level in drinking water. Removal of the heavy metals from the resin was successfuly perfomed with 3 M HCl or HNO3.
