Spectrophotometric determination of zirconium and other colour reactions by galangin

  • Mohan Katyal

The spectrophotometric determination of zirconium is described, based on the formation of a yellow coloured complex between zirconium and galangin. Maximum absorption by the reaction product only at one specific wavelength (410 mµ) in the acidity range of 0·5 N-HCl to pH 4·5, suggests the formation of only one complex. The complex, not extractable by usual organic solvents, has been studied in 40% alcoholic medium. It obeys Beer’s law from 1 to 6 p.p.m. of metal ion concentration and contains the two components in the molar ratio of 1:1. The effect of the reagent on other ions has been qualitatively studied. Also, the effect of foreign ions on the complex has been investigated.
