Microamount determination and extraction of Mn(VII),Ni(II) as anion in different Vital and environmental samples with 2-[α-naphthol azo]-4,5-diphenl imidazole[α-NADPI]

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.
