Synthesis and absorption properties of new Na specific adsorbentLi1+xAlxTi2-x(PO4)(3)

A new kind of adsorbent Li1+xAlxTi2-x(PO4)(3) was synthesized by solid state reaction method. The influence of the content of doping aluminum on the adsorbent Li1-xAlxTi2-x(PO4)(3) was investigated by XRD, while the morphology of powders was observed by SEM. The investigation of the adsorption properties showed that the adsorbent can selectively adsorb sodium with the adsorption capacity of 11.76 mg/g. The optimum conditions of adsorption are at pH 10.0-11.0 in LiCl solution. A new kind of adsorbent Li1+xAlxTi2-x(PO4)(3) was synthesized by solid state reaction method.
