Abstract: A noveI method is described for the simultaneous extraction and direct spectrophotometric determination of vanadium wit dibenzo- 18-crown-6 from 1.0 mol dm- 3 potassium thiocyanate containing 3.0 mol dm-3 hydrochloric acid solution. The effect of concentrations of hydrochloric acid, potassium thiocyanate, crown ethers and role of diluents has been studied. Vanadium has been separated from many mixtures, containing, lead, cadmium, chromium, thallium cerium, thorium and yttrium which are generally associated in ores, alloys and in steel samples. The proposed method is simple, sensitive, rapid, selective and permits extractive separation and direct spectrophotometric determination in one single operation.
