Abstract

Rare earth-T4(L-thyroxine) systems were studied with pH potentiometry in the mixed solvents (DMSO/H₂O=50% V/V)(37C , 0. 15 mol·L^-1NaCl). The protonation constants of T4 and the stability constants of the rare earth complexes with T4 (RE=Pr, Eu, Gd, Tb, Yb) were obtained. The results of UV, HNMR and fluorescence spectra studies show that T4 can coordinate to are earth ions through its -COO- group at lower pH value and via its -NH₂ group at higher pH value also. The coordination bonds of the complexes are predominantly ionic.
