摘要
本文用自己设计的四电极系统线路-改装的79—1型伏安分析仪,作了钡离子与18-冠-6形成的配合物在油/水界面离子迁移的研究。试验结果表明,由18-冠-6推动Ba^(2+)离子的迁移是受扩散控制的可逆过程。此迁移过程可描述为: Ba^(2+)(w)+L(n,w)BaL(w,n)
In this paper we study the transfer of Ba ion across the aqueous/organic phase interface by means of improving 79-1 type voltammeter with four electrode cell system. The result showed that the transfer process Ba ion facilitatcd by 18-crown-6 is a reversible one controlled by diffusion. The translocation can be described as the formation of the complex between Ba(Ⅱ) and crown, Ba(Ⅱ)(w)+L(n,w)=BaL(w,n).
