摘要

采用二芳基对叔丁基杯[4]芳烃与聚（氯乙烯）叠氮化物（PVC-N3）的点击反应合成了一种新的合适材料。这种新型的具有三唑基团的二芳基对叔丁基杯[4]芳烃接枝到PVC聚合物（PVC-0.75CX[4]）上，对水溶液中的铬离子具有优异的萃取能力。由于软腔、π-三唑环和氢键的存在，它显示出从水溶液中提取铬（VI）离子的独特能力。在pH=3时，Cr（VI）离子的吸附能力为95.5%。

Poly(vinyl chloride)-supported triazoles grafted onto calix[4]arene for chromium ions extraction

A new suitable material was synthesized using click reaction between dialkynyl-p-tert-butylcalix[4]arene and poly(vinyl chloride) azide (PVC-N3). This novel dialkynyl-p-tert-butylcalix[4]arene with triazole groups grafted onto PVC polymer (PVC-0.75CX[4]) has an excellent extraction capability for chromium ions from aqueous solutions. It shows a unique ability to extract chromium (VI) ions from aqueous solutions, thanks to the soft cavity, the presence of π-triazole rings and hydrogen bonds. Cr (VI) ion sorption capacity is 95.5% at pH = 3.
