摘要：

P-carboxyphenyl azo calix[4]arene phosphate derivative (P-CACPD) was successfully synthesized using calix[4]arene as raw material. The P-CACPD was characterized by FT-IR and 1H-NMR. The effects of pH, extraction time and temperature on the extraction of U(VI) by P-CACPD were investigated. The results show that pH value, extraction time and temperature have an effect on the extraction of U(VI) by P-CACPD. When the initial pH is 5, temperature is 25 °C, extraction time is 2 h, the extraction rate of U(VI) by P-CACPD reaches the maximum. Both kin...
