| 摘 要： | 合成了对叔丁基杯［4］芳烃及其衍生物--对叔丁基杯［4］芳烃乙酸，并研究了其对钍（Ⅳ）离子的吸附性能。紫外光谱法研究表明，杯芳烃衍生物在pH=3、30℃下震荡2h后达到吸附平衡，对钍离子的吸附率达72%，吸附容量为9.0mg/g。干扰离子研究结果显示，带羧基的杯芳烃衍生物有望成为钍（Ⅳ）离子的良好吸附剂。

| Abstract: | P-tert-butylcalix［4］arene［PTBC］ and its derivative p-tert-butylcalix［4］arene acetate［PTBCA］ were synthesized and its adsorption properties of Th4+ were studied. UV-spectrophotometric analysis shows that the adsorption of thorium using the PTBCA can reach adsorption equilibrium within 2h under the condition of pH=3 and temperature of 30℃. The adsorption rate is 72% and the adsorption capacity is up to 9.0 mg/g. Interfering ions research shows that calixarene derivatives with a carboxyl group is expected to be a good adsorbent for Th4+. |
