An ultramicro-scale method for the determination of the uranyl cation

Abstract

A method that requires the use of very simple equipment has been developed whereby the uranyl cation can be determined at the micro-scale and ultramicro-scale levels with high precision. The method involves the use of the catalytic effect shown by the uranyl cation on the photo-decolorisation of a naturally occurring carotenoid-type pigment. The interfering effects of several common anions and cations are also discussed.
