- 中文摘要: Iron and cobalt complexation with salicylaldehyde hydrazone (SH) has been studied spectrophotometrically employing solvent extraction technique. The Fe(III)-SH (1:3) and Co-SH (1:2) complex absorb at 510nm 450nm respectively. The sensitivity of the colour reactions are 0.014 and 0.005 in terms of Sandell’s definition for iron and cobalt systems. Both the complexes show maximum and constant absorbance in the pH range 3.5 to 5.0 and 6.2 to 7.0 for Fe(III)-SH and Co(II)-SH respectively. The complexation has been used in the spectrophotometric determination of iron and cobalt in coexistence with several ions.
