氮杂冠醚对碱金属苦味酸盐液膜传递性能的研究

STUDY ON THE LIQUID MEMBRANE TRANSPORT OF ALKALI PIRATES USING AZOCROWN ETHERS AS IONOPHORES

本文以四种二苯并氮杂冠醚为离子载体，以二氯甲烷为有机液膜，研究了其对碱金属苦味酸盐（钠和钾）的液膜传递性能。结果表明。

The liquid membrane transport of alkali me tal ions(K+ and Na+) using four dibenzoacrown ethers as ioncarriers was st udied. The results show that the transport rates are closely related to whether the cavity of the crown ether fits well with the size of the ion.
