Abstract

Joining solvent extraction with cloud point extraction methods obtained a susceptible method for separation, pre-concentration, extraction and categorization of  Zn (II), after forming an ion-pair association complex between Zn+2 and 4-(3-methyl phenyl azo)-4,5- diphenyl imidazole (MPADPI) with wavelength for maximum absorbance λmax.=496 Nm. This study shows optimum conditions for the formation and exaction ion-pair association complex under pH=9 and 0.5 mL Tritonx-100, 1×10-4 M (MPADPI) and heating at 80 Co for 20 minutes so that this study involved the effect of electrolyte and interferences along with the spectrophotometric determination of Zinc (II) in diverse samples.
