A red-violet ternary complex of scandium with GCR and CTMAB is formed in a weak acid solution. The maximum absorption. of the ternary complex is at 540nm with apparent molar absorption coefficient of 4.14×10⁴. The composition of ternary complex is found as: Sc:GCR:CTMAB=1:2:2. For the Sc dertermination the interfreences of the diverse ions was reduced by masking with a mixture of acetylaceton and phenanthroline.The method has been used satisfactorily to determine small amount of Sc in the synthetic mixture of rare earths.
