An investigation of the complex formation between Cadmium(II) and Potassium iodide in Sulphuric acid solution has been carried out and its extractability by high molecular weight tertiary amine (HMWA) in organic solvent was examined. The yellow colored complex of Cd(II)-I2 is quantitatively extractable into organic phase containing tribenzyle amine. On the basis of this extractability a method has been developed for the spectrophotometer determination of Cadmium in the presence of many other interfering radicals. The extractability of the Potassium iodide complex by HMWA suggests that the colored species is anionic. Source
