Abstract
This work amid to determine of Ni(II) and Co(II) by using 2-[(2-Carboxy-4-nitrophenyl) azo]-4,5-diphenyl imidazole (CNPAI), maximum absorption of two complexes are 566nm and 592nm for Ni-CNPAI and Cd-CNPIA respectively while the maximum absorption of the ligand was 425nm.
Optimum condition were constructed, calibration curve was obeyed in the range (0.05-1.3) ppm for Ni and (0.1-8) ppm for Co ions, the linearity ( R2 ) was (0.9991), (0.9995), molar absorpitivty (ε) was 1.7448 x 104 L.mol-1.cm-1, 9.908 x 104 L.mol-1.cm-1 for Ni(II) and Co(III) complex.
The stoichometry of metals to reagent were 1:2 for two complexes, Precision and accuracy of the analytical procedure for Ni(II) and Co(II) were R.S.D % (2.11 , 0.82)%, (Erel., Re) % were (-3.1, 96.9) % and (-2.7, 97.3) %.
