摘　　要：Bis[1-hydroxyalkylbenzo]-21-crown-7 (A-C) have been synthesized by ) two-step reactions from dibenzo-21-crown-7 (DB21C7). Extraction of cesium cation from nitric acid solutions by A-C has been investigated in nitromethane. Under the conditions of various concentration of HNO3 or NaNO3, the extractabilities of A and B were superior to that of DB21C7. 关键词：铯 4(5),4'(5')-二[1-羟烷基苯]-21-冠-7 萃取核放射废物
