摘　　要：用一锅法合成了4种磺酸酯桥联杯芳烃化合物,用它们作萃取剂,以氯仿为溶剂,用原子吸收的方法测定了它们对水溶性的Ca2+、Pb2+及部分过渡金属10种金属盐的萃取作用。结果表明,此类杯芳烃对Cr3+、Cd2+和Co2+等几种有毒有害的离子有良好的选择性识别作用,其中化合物2a对Cr3+、化合物2b对Cd2+的萃取率分别达到了50.15%和46.48%。Four aromatic tetrasulfonate calixarenes have been prepared in one pot and melr extraction performances toward Ca^2＋ , Pb^2＋ and some transition metal ions in chloroform were evaluated. The primary results revealed that the sulfonate-bridged ealixarenes showed improved extraction capabilities toward several toxic cations such as Cr^3＋ , Cd^2＋ and Co^2＋ The extracted percentages of Cr^3＋ by compound 2a and Cd^2＋ by compound 2b are 50. 15% and 46. 48%, respectively.
