A new method recently presented by Mench et is based on the affinity of Fe and Mn oxides (or sulfates) to adsorb and occlude several trace elements from the ambient solution. Application of steel shots containing mainly Fe (over 90%) and oxides of other metals in negligible amounts (below 1%) resulted in immobilization of considerable ...
