Determination of scandium by atomic absorption.

A comprehensive study has been made of the determination of scandium by atomic absorption. In addition to the instrumental variables such as flame-height, slitwidth and lamp current, a number of solution variables have been studied including the effect of anions (chloride, sulfate, nitrate, and fluoride), organic solvents, and other metals on the determination of scandium. Standard conditions have been established for the detection of minor amounts of scandium in a wide variety of materials including complex alloys of iron, nickel, aluminium, magnesium, and the rare earths.
