Abstract
Ion-exchanger phase spectrophotometry with p-nitrochlorophosphonazo (C PApN) has been developed for the determination of scandium. The linear range is 1-8 mu g of scandium in 50 ml of solution, using 0.8 g of re sin, with an apparent molar absorptivity of 2.76 x 10(5) l mol(-1) cm( -1). Aluminum and rare earth elements in reasonable amounts do not int erfere. The method has been applied successfully to the determination of scandium in alloys, with relative standard deviations of 2-4%.
