Abstract: The principle of free floating factor analysis (FFFA) is described. In the dual colour developing system of RE-TBA and RE-MTB-CPB, we successfully determined the four component rare earth mixtures of La, Sm, Dy and Lu simultaneously using this method. The optimum conditions for the simultaneous determination of the four elements are also discussed.

Key words: Free floating factor analysis, Rare earth, Simultaneous determination
