Abstract

An HPLC method has been developed for the separation of new complexes of tetrakis(4‐methoxylphenyl)porphyrin (TMOPP) with four heavy rare earth elements (RE = Y, Er, Tm, and Yb). The function of amine and acid in the mobile phase has been investigated and a reasonable explanation is presented. Successful separation of the RE‐TMOPP‐Cl complexes is accomplished in 10 min with a mobile phase consisting of methanol‐water‐acetic acid‐triethanolamine. The detection limits (S/N = 3) for the four complexes are 0.01 μg/mL. This method is rapid, sensitive, and simple.
