Abstract

The radiolytic stability of 25,27-bis(2-propyloxy)calix[4]-26,28-crown-6(iPr-C[4]C-6) was studied. The radiation source was 60Co and its dose rate was 437 Gy/min and the total absorbed dose was from 104 to 106 Gy. The iPr-C[4]C-6 solid and 0.025 mol/L iPr-C[4]C-6/n-octanol which were pre-equilibrated with 0.01 and 3 mol/L nitric acid, respectively, were absorbed different dose and their extraction performance were researched. The degradation mechanism of them was investigated by mass spectrometry and infrared spectrum. The results show that radiolytic stability of the iPr-C[4]C-6 solid and 0.025 mol/L iPr-C[4]C-6/n-octanol are good when their absorbed dose was less than 106 Gy. The extracting system of iPr-C[4]C-6/n-octanol is promising for separating cesium from high level liquid waste.
