摘要：
A very sensitive extraction spectrophotometric method for the analysis of uranium based on the extraction of a uranium-benzoate-crystal violet complex by a mixture of xylene and benzene is described. The absorbance maximum is at 606 nm and molar absorptivity is 4.28·104 l·mol-1·cm-1. The interference due to a number of anions and cations studied without any pre-extraction was found to be within permissible limits. The method has been used for determining uranium in a synthetic solution, i.e., uranium in the presence of various other ions. The interference due to some cations was eliminated by the use of a masking agent (boric acid). © 1979 Akadémiai Kiadó.
