Spectrophotometric study on the uranium complexes with 4-(2-thiazolylazo) resorcinol in the presence of zephiramine

Journal Article · · Anal. Lett.; (United States)

The effect of tetradecyl-dimethyl-benzyl-ammonium chloride (zephiramine=z/sup +/Cl/sup -/) on uranium with 4-(2-thiazolylazo)resorcinol (TAR) was studied. In the presence of zephiramine, a uranium-TAR complex was stabilized and solublized in aqueous media at a pH around 7. The addition of zephiramine made it possible to use phosphate buffers which have large buffer capacity in the optimum range for the determination of uranium. Almost all interfering ions can be masked with an EDTA solution. 5 figures, 2 tables.
