A new heteronuclear complex, rare earth(III)-copper(II)-m-trifluomethyl chlorophosphonazo (CPA-mCF{sub 3}) system for determining trace rare earth ions is presented. In a medium of 0.02mol/L NH{sub 4}Cl, 1.0 x 10{sup -3} mol/L Cu(II), 1.0 x 10{sup -5} mol/L CPA-mCF{sub 3}, a very sensitive polarographic adsorptive wave is observed by using a single sweep oscillopolarograph at about -0.83V (vs. Ag/AgCl). The linear relationship between the peak current and the concentration of rare earth exists from 6.0 x 10{sup -9} to 1.0 x 10{sup -6}mol/L. The detection limit of rare earth is down to 2.0 x 10{sup -9} mol/L for Tm{sup 3+}.
