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

Abstract

Abstract: A cloud point extraction-chromogenic system for vanadium determination containing 4-(2-thiazolylazo)resorcinol (TAR), H2O2, H2SO4, and Triton X-100 was investigated. Optimal conditions for the formation and extraction of a 1:2:1 (VV:O2 2−:TAR) t
