Some biologically active uranyl compounds like uranyl nitrate, uranyl zinc acetate, uranyl nickel acetate were monitored upto 10-4 M by graphite paste voltammetry in aqueous solutions of 0.1 M KCI, 1.0 M HCI and 1.0 M CH3COOH as supporting electrolyte. These systems showed oxidation or reduction or reduction waves in the range + 0.24 to + 0.7 V and -0.4 to -1.0 V vs saturated calomel electrode at silicone oil and -chloronaphthalene impregnated graphite paste electrode. -chloronaphthalene was used as a "binding agent" in lieu of -bromonaphthalene which has never been reported before. This method be characterized by its simplicity, reproducibility of the test electrode surface, a well extended working anodic range ( + 1.40 V) and least interference from dissolved oxygen (Peak).
