S>A new spectrophotometric method for the determination of scandium is described using anthrarufin-2,6-disulfonic acid (disodium salt) as a reagent. The color reaction has a sensitivity of 0.004 g Sc per cm/sup 2/ for log I/ sub o//I = 0.001 and obeys Beer's law up to 2 ppm. The effects of pH, time, order of addition of the reagents, temperature, and diverse ions were investigated. A separation procedure was developed and applied to six salt solutions containing scandium plus a variety of foreign ions. (auth)
