Physicochemical characterization of La₂(CO₃)₃.4H₃O, a new and promising agent for the treatment of hyperphosphatemia

Resumen

The synthesis of La₂(CO₃)₃.4H₂O was carefully investigated, on the basis of the thermal behavior (TG and DTA measurements) of the corresponding octahydrate, used as the precursor. The analysis of the X-ray powder diagrams of La₂(CO₃)₃.4H₂O showed that this hydrate crystallizes in the tetragonal crystal system with Z = 8. The FTIR and FT-Raman spectra of La₂(CO₃)₃.4H₂O and of La₂(CO₃)₃.4H₂O were recorded and assigned. The usefulness of the tetrahydrate for the treatment of hyperphosphatemia is briefly discussed.
