| Abstract | ||
| 2-[Benzo thiozolyl azo]-4-Benzyl phenol (BTABP)was used as an organic reagent to form complex with Lead(II) having maximum absorbance at (λ=393 nm) and molar absorbency ε=2121 L mol-1cm-1.The optimum condition studies about complexation reaction demonstrated PH=9, 25minutes shaking time, stoichiometry shows the complex have a structure of 1:2(metal:ligand) [Pb+2(BTABP-)2] ,as well complexation reaction was endothermic reaction without any effect for polarity of organic solvent on extraction method but there is effected for organic solvent structure ,in addition of used this organic reagent as spectrophotometric reagent for determination of Lead(II) in different samples of plants soils and water at different position in Al- Najaf governorate, with RSD%=1.2 , DL=3.492×10-6 and Sandell,s sensitivity S=9.77×10-7mg cm-2. | ||
