A multi-phase model was developed and Tb(Ⅲ) speciation in human blood plasma was studied. At a concentration below 3.744×10^-4mol/L (or at the concentration), Tb(Ⅲ) is mostly bound to phosphate to form precipitate of TbPO₄. As the concentration of Tb(Ⅲ) increases,phosphate is exceeded and another kind of precipitate of Tb₂(CO₃)₃ appears. Among soluble Tb(Ⅲ) species, Tb(Ⅲ) mainly distribute in [Tb (Tf)] at low concentration and in [Tb (HSA)], [Tb₂(Tf], [Tb (IgG)], [Tb (Lactate)]²⁺, [Tb (CitArgH)] and free Tb(Ⅲ) at high concentration.
