Abstract

Calix[6]arene carbon chain alkyl sulfoxide derivative have been successfully synthesized. IR spectra confirmed the introduction of sulfoxide group on calix[6]arene. UV spectra indicated that calix[6]arene sulfoxide derivative has a high complexation of uranium. The coordination ratio between the calix[6]arene sulfoxide derivative with uranium is 3:2, which was determined by Job’s method. Extraction experiments showed that the extraction efficiency of uranium is able to achieve 73.8%, which suggested the potential application of calix[6]arene sulfoxide derivative as an excellent uranium extraction agent.
