Spectrophotometric determination for microamount of mercury (ІӀ) and zinc(ІӀ) from HCl media by Rhodamine 6G
Abstract
Rhodamine 6G used as anion exchanger in organic phase for extraction and spectrophotometric determination of Hg2+ and Zn2+ ions from HCl aqueous media after conversion metal ions into chlorol complexes anion .The study include limitation optimum condition for extraction such as , HCl concentration , metal ion concentration shaking time as well as stoichiometry of ion pair complex extracted , organic solvent effect , thermodynamic studies about extraction was endothermic for both metal ions ; in addition to another studies and applications for determination analyte metal in different samples .
