ABSTRACT

Effluents from textile, leather, tannery, electroplating, galvanizing, pigment and dyes, metallurgical and paint industries, and other metal-processing and refining operations contain considerable amounts of toxic metal ions. Of the important metals, mercury, lead, copper, nickel, cobalt, cadmium, and chromium (VI) are regarded as highly toxic [1]. Radionuclides, such as uranium, possess high toxicity and radioactivity, and exhibit a serious threat, even at small concentrations, to the health of human beings [2].
