Abstract
2 - Thioorotic Acid (Amm. Salt) has been used as a selective reagent f or the potentiometric estimation of Hg(II) ions at microgram levels, w ith an error of 0.4% at 5000mug/l, increasing up to 1.0% at 100mug/l. The method has been found free from the interfering effects of Cl-, Ca ++, Mg++, and Fe++, which are usually present in environmental samples , and applied successfully to the estimation of Hg(II) in chloroalkali effluents. Compared to the colorimetric dithizone method, the potenti ometric method using the new reagent has been found to be more sensiti ve and simple in operation.
