Aiming at selective adsorption and separation of Y(III) from the Y(III)–Sr(II) group in acid solution, a silica-based TODGA impregnated adsorbent [(TODGA+1-dodecanol)/SiO₂–P–F600] has been prepared. Batch adsorption experiments were conducted under the effect of contact time, acid concentration, solution temperature, and adsorption capacity etc. Chromatography recovery of more than 90% Y(III) was successfully achieved under elution with 0.01 M DTPA solution in nitric acid adsorption system, and 0.1 M HCl solution in hydrochloride adsorption system, respectively.

多孔硅胶基吸附剂对酸性溶液中Y(III)和Sr(II)的吸附分离行为

针对酸性溶液中 Y(III) 与 Y(III)–Sr(II) 基团的选择性吸附和分离，二氧化硅基 TODGA 浸渍吸附剂 [(TODGA+1-十二烷醇)/SiO ₂ –P–F600]已经准备好了。在接触时间、酸浓度、溶液温度、吸附容量等影响下进行批量吸附实验，在硝酸吸附系统中用0.01 M DTPA溶液洗脱，成功实现了90%以上Y(III)的色谱回收率，和 0.1 M HCl 溶液在盐酸盐吸附系统中。
