摘　　要：本文以杯冠BEHBCalixC6为萃取剂,二氯甲烷为稀释剂,通过液液萃取,研究了BEHBCalixC6对苦味酸铯的萃取性能。研究表明,随着主、客体摩尔比的增加,萃取率增大。在摩尔比50∶1时,萃取率可以达到77%以上。考察了测量参比溶液、预饱和两相稀释剂、稀释剂种类和溶液中Na+浓度等因素对萃取率的影响。In the present work extraction towards cesium picrate with calix[4]arene-bis[4-(2-ethylhexyl) benzo-crown-6](BEHBCalixC6) as extracnt was investigated in dichloromethane via liquid-liquid extraction.The results indicated that the extraction efficiency increased with increment of the molar ratio of host and guest.At 50∶ 1 of the molar ratio,the extraction percentage reached over 77%.In addition,the effects of diluent,pre-saturation of the diluent and reference solution for measurement and the concentration of Na+ were examined as well.
