摘要：
It was demonstrated that traces of rare earth elements (REEs) can be quantitatively preconcentrated from contaminated water with pH >= 3 on a silica-based adsorbent with covalently immobilized amino-di(methylenephosphonic) acid (SiO2-AdPA). However, recovery of REEs from the adsorbent required utilization of a strong mineral acid. In order to reduce environmental impact and increase the reusability of the adsorbent, a ligandexchange approach that includes treatment of the adsorbent with strong complexing ligands was used. The eluting potential of several ligands was investigated, namely EDTA, 5-sulfosalicylic acid (SSA), citric acid (CiA), aminosulfonic acid (AmSA), alpha-hydroxyisobutyric acid (HBA), oxalic acid (OxA) and ascorbic acid (AsA). The results were compared to those obtained by acidic treatment (HCl or HNO3). It was demonstrated that the complete desorption of all REEs can be achieved by using 10(-2) mol L-1 EDTA solution with pH = 8.0, while acidic treatment requires 1.0 mol L-1 HNO3. Reusability tests demonstrated complete stability of the adsorbent for at least five consecutive adsorption/desorption cycles with no decrease in its adsorption characteristics.
