A multi-phase model of Pr(Ⅲ) speciation in human interstitial fluid was constructed and insoluble Pr(Ⅲ) speciation was studied. When the total concentration of Pr(Ⅲ) is below 8.401E-10 mol/L, soluble Pr(Ⅲ) species are main species. With rising the total concentration of Pr(Ⅲ), Pr(Ⅲ) is firstly bound to phosphate to form precipitate of PrPO₄, then bound to carbonate and another precipitate of Pr₂(CO₃)₃ was obtained. When the total concentration is between 1.583E-9 mol/L and 4.000E-3 mol/L, the insoluble species are predominant Pr(Ⅲ) species.
