Abstract
Sensitive solvent extraction method with Cloud point Extraction method used for determination of Zinc (II) by organic reagent N-(5,6-dimethoxypyrim-idin-4-yl)-4-((4,5-diphenyl-1H-imidazol-2-yl)diazenyl)benzenesulfonamide and studies ion pair association complex for (NDPDBS) and Zinc2+ in acidic HCl medium shows the wave length of maximum absorbens was λmax=294nm , all studies about optimum condition for giving higher extraction method where, PH=9 as optimum in presence 50 µg Zn2+ in 10 mL aqueous solution, 0.5 mL surfactant Triton X- 100 , and heating temperature at 90 C ̊ For 15 min , 1×10-4 M (NDPDBS), The stoichiometry show up the composition of ion pair association complex extracted was 1:1 , and addition to other studies such as effect of interferences, electrolyte and else , Statistical values were also recorded for LOD = 0.13904674 ppm ,LOQ = 0.42135377 ppm and Sandell’s sensitivity (2.33×10-3 μg/cm2) .
