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。
P-tert-butylcalix[4]arene[PTBC] and its derivative p-tert-butylcalix[4] arene acetate[PTBCA] were synthesized and its adsorption properties of Th^4+ were studied. UV- spectrophotometric analysis shows that the adsorption of thorium using the PTBCA can reach adsorption equilibrium within 2 h 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 Th^4+.
