The value of pH50 (the pH at which 50% adsorption occurs) followed the sequence Zn > Cu > Pb > Cd in single-element systems, but Pb > Cu > Zn > Cd in the multi-element system. Adsorption isotherms at pH in the multi-element systems showed that there is competition among various metals for adsorption sites on BOF slag.
