A simple cloud point extraction-spectrophotometric method for total vanadium determination using 4-(2-thiazolylazo)resorcinol and H2O2

A cloud point extraction-chromogenic system for vanadium determination containing 4-(2-thiazolylazo)resorcinol (TAR), H 2 O 2 , H 2 SO 4 , and Triton X-100 was investigated. Optimal conditions for the formation and extraction of a 1:2:1 (V V :O 2 2− :TAR) ternary complex with an absorption maximum a...
