Microamount determination and extraction of Mn(VII),Ni(II) as anion in different Vital and environmental samples with

Abstract

Extraction Ni(II) as anion chloro complex [NiCl4]= and Mn(VII) as [MnO4] - as ion pair complex extracted to organic phase by un organic reagent 2-[α-naphthy azo]-4,5-diphenyl imidiazole [α-NADPI] as complexing agent , with definition all parameters effect on extraction activity such as, hydrochloric acid concentration, metal ion concentration, shacking time, as well as stoichiometry show ion pair complex extracted was 1:1:1. Thermodynamic study appear the complexation reaction was endothermic with both anion [NiCl4]= and [MnO4] -, in addition to used this method to determination Ni(II) and Mn(VII) in different environmental and vital sample.
