| 摘 要： | Li~-和H~-因较强的亲水性,较难穿越液/液界面进行传输。本文报道了冠醚双环已基18冠6对Li~+,Na~+,Rb~-和H~-在水/硝基苯界面的促进传输行为,求得了相应促进传输过程的一系列参数,并对被传输离子在传输过程中的形态变化进行了初步的探讨。

| Abstract: | Because of the strongly hydrophilic characteristic ,Li+ and H- can hardly be transferred across the liquid/liquid interface. The accelerative effect of dicyclohexane-18-crown-6 on the transfer processes of Li+. Na+ ,Rb+and H+ from the aqueous to the organic phase and thermodynamic parameters of the processes were investigated,and the form change of the ions during the facilitated transfer was discussed. |
