摘要	A series of novel kind of Na+ specific adsorbent compounds Li1+xLaxZr2-x(PO4)(3) were synthesized by high temperature solid state reaction method. The samples were characterized by XRD, SEM, IR techniques and their adsorption performances were investigated. XRD analysis showed that a structure of LiZr2(PO4)(3) could be found in the composition range of x <= 0.4. SEM analysis showed that they were highly dispersive particles with diameters of 5 similar to 20 mu m. The investigation of the adsorption properties showed that the low concentration La dopant (x <= 0.4) made it adsorb sodium selectively, and also confirmed that the La ion dopant was an effective method to improve the adsorption properties. The exchange capacity was 48.3 mg/g, under x=0.4, pH=10.0 similar to 11.0 in LiCl solution.
