Abstract
Simultaneous separation and determination of organic (methyl, ethyl, propyl, butyl halide and phenyl acetate) and inorganic mercury in water and industrial waste by dithizone extraction method has been developed. Dithizonate of both organic and inorganic mercury salts are quantitatively separated with acidic potassium iodide solution. Organic mercuric dithizonate is further decomposed to inorganic mercury with acidic potassium permanganate solution. By this method, organic and inorganic mercury can be determined at levels of 0.001-0.02 ppm. Effect of chlorine ion, copper, and zinc is negligible.
