ALKALI AND ALKALINE-EARTH METAL-ION TRANSFER ACROSS THE LIQUID-LIQUID INTERFACE FACILITATED BY IONOPHORE ETH157

The H+, Li+, Na+, K+, Mg2+, Ca2+ and Ba2+ ion transfer across the water/nitrobenzene (NB) and water/1,2-dichloroethane (DCE) interfaces, facilitated by the ionophore ETH157, has been investigated by cyclic voltammetry (CV). The mechanism of the transfer process has been discussed, and the diffusion coefficients and the stability constants of the complexes formed in the nitrobenzene phase have been determined.

中性载体ETH157推动Cu~(2+)离子在水/硝基苯界面上的转移

本文用循环伏安法研究了中性载体ETH157推动Cu~(2+)离子在水/硝基苯界面上的转移过程,结果发现在水/硝基苯界面上,Cu~(2+)离子与ETH157形成了逐级配合物,并伴有吸附现象产生,考察了有关过程的转移机制并讨论了相应的实验现象。
