| Research Abstract |
I have developed some new functional materials which appear through stable complexation with lanthanide (Ln(III)) ions for selective separation of rare metals. I prepared O and N-donor atoms as different PTA ligands. Then the PTA ligands were successfully anchored onto mesoporous ilica. The data also revealed that EXAFS data of specific Ln(III)-ligands complex were the same as Ln(III)-ligands-mesoprous materials which was very interesting and exceptional the solid functional mesoporous materials for Ln(III) ions recovery. The most significant point was: Ln(III) sorption was not affected by the presence of monovalent and divalent of sodium, potassium, calcium, magnesium, chloride, sulfate and nitrate ions due to strong tendency to form stable complexation with trivalent Ln(III). The EXAFS data revealed that O and N donor atoms of the nano-adsorbent were strongly coordinated to Ln(III) ions to form stable complexes.
