合成了一种大环超分子识别剂1，3-双(1-壬氧基)-2，4-冠-6-杯[4]芳烃。研究了在硝酸介质中，非杯[4]C6/正辛醇对发热剂Cs(I)和一些典型的裂变和非裂变产物La(III)、Y(III)、Rb(I)、Mo(VI)、Zr(IV)、Sr(II)、Ba(II)、Ru(III)、Na(I)、K(I)和Pd(II)的萃取。考察了接触时间、硝酸浓度在(0.4~5.0)m ol·kg-1范围内和温度对去除效果的影响。除Rb(I)外，非杯[4]C6对Cs(I)具有较好的萃取能力和较高的选择性，这归因于非杯[4]C6对Cs(I)的有效识别。萃取Cs(I)的最佳酸度为4.0mol·kg-1HNO3。讨论了Cs(I)的萃取性能和机理。Cs(I)与非杯[4]C6的萃合物组成为CsNO_3·非杯[4]C_6。得到了萃取Cs(I)的有价值的化学工程参数。它..。
A macrocyclic supramolecular recognition agent, 1,3-bis(1-nonyloxy)-2,4-crown-6-calix[4]arene (NonCalix[4]C6), was synthesized. The extraction of Cs(I), a heat generator, and some typical fission and nonfission products, La(III), Y(III), Rb(I), Mo(VI), Zr(IV), Sr(II), Ba(II), Ru(III), Na(I), K(I), and Pd(II), with NonCalix[4]C6/1-octanol in HNO3 medium was investigated. The effects of contact time, the concentration of HNO3 in the range of (0.4 to 5.0) mol·kg–1, and temperature were evaluated. NonCalix[4]C6 showed excellent extraction ability and high selectivity for Cs(I) over the tested metals except Rb(I), which was ascribed to the effective recognition of NonCalix[4]C6 for Cs(I). The optimum acidity in the extraction of Cs(I) was 4.0 mol·kg–1 HNO3. The extraction property and mechanism of Cs(I) were discussed. The composition of the extracted species of Cs(I) with NonCalix[4]C6 was determined as CsNO3·NonCalix[4]C6. Valuable chemical engineering parameters in the extraction of Cs(I) were obtained. It ...
