Development and use of the kinetic method for determination of trace amounts of vanadium (V) in water samples from objects of the environment

Abstract

A new kinetic method has been developed for simple, fast and selective determination of trace amounts of vanadium (V) (0.5-5 μg/cm 3 ) based on its inhibiting effect on the oxidizing reaction of 4 hydroxicumarine by means of KMnO 4 in acid media. The proposed kinetic method was used for determi nation of vanadium (VP) in different samples of water without its preliminary separation.
