The determination of the total amount of rare earth (RE) in aluminum and its alloys was established by using AGA-CPA as chromogenic reagent. The optimum conditions of the binary system were studied. The composition of the complex was RE: AGA-CPA = 1: 3. The influence of more than 30 kinds of coexisting ions on the determination was studied and successfully applied to the determination of rare earth Determination of the total amount
