摘要The coordination chemistry of Calix[4]arene-biscrown-6 (BisC6) with Cs+ was studied in solution. The extraction experiments demonstrated that Cs+ extracting percentage at the single stage was 99.36% in o-nitrophenyl methyl ether (NPME) at room temperature. In simulated HLLW, the separation factor of Cs+/Na+ and Cs+/K+ is 3.92 x 10(4) and 2.21 x 10(4) respectively. The local structure model of the complex showed that HNO3 or H2O might be located in the complexes. ESI-MS showed that the cesium ion complex with BisC6 might form both 1 : 1 (mononuclear) and 2 : 1 (bisnuclear) Cs+: ligand species and [BisC(6) center dot H2O], [BisC6 center dot Cs+](+), [BisC(6) center dot 2Cs(+) center dot H2O](2+), [BisC6 center dot 2Cs(+) center dot NO3-](+) etc. might exist in BisC6/NPME/HNO3 system. The EXAFS results indicated that the coordination number of cesium in BisC6 was seven and the complex structure with seven-oxygen coordination was stable. ADF computation verified the EXAFS results.
