In-vitro treatment of water samples with added poUutants, that are found in many polluted waters, reveals that the saw-dust of Albizia Odoratissima ("mara" in SinhaIa) is able to remove many metal ions such as magnesium, calcium, chromium, manganese, iron, cobalt, copper, zinc, cadmium and lead from polluted waters. However, water samples treated with mara saw-dust for colour removal is not clear enough to be discharged into surface water without further treatment. Nevertheless, such methodology offers unique advantages of treatment of polluted water in developing countries.en-USPolluted waterIn-vitroArticle
