With the heightened awareness of the need to protect the environment, industry has been forced to deal with increasingly stringent environmental regulations. A growing number of methods to remove pollutants from waste water are utilized in industry. The purpose of this research was to remove heavy metals from aqueous solution by encapsulation. The method involved the addition of concrete and other materials which entrap the heavy metals. The concentrations of metals were determined by atomic absorption. Three different treatments were used and were shown to be effective in removing zinc and iron. It was also found that the detection limit of atomic absorption was not sufficiently low to compare the effectiveness of the treatments.
