SCREENING OF SOME TRANSITION METAL IONS AND QUANTITATIVE DETERMINATION OF COPPER, CADMIUM AND ZINC BY SOLID PHASE DERIVATIVE SPECTROPHOTOMETRY
A simple solid phase spectrophotometric method for both screening of eight transition metal ions plus lead and quantitative determination of copper, cadmium and zinc is described. The method is based on the preparation of a sensitive analytical zone by immobilization of the organic reagent 1-(2-pyri...
