Abstract: The extraction behavior of rare earths with HPMCP-petroleum ether has been studied. Experimental results showed that rare earth ions as Ln(PMGP)3·HPMCP form were extracted into organic phase. Their extractive constants 1gKwere calculated by the slop method. On the basis of this, their solid complexes were produced. The constitution of solid complexes is Ln(PMCP)3·2H2O. Their spectrum, IRand NMR were also studied.
