乳化剂OP存在下二安替比林甲烷推动镝(Ⅲ)在油/水界面的转移

THE DYSPROSIUM ( Ⅲ ) TRANSFER ACROSS WATER/OIL INTERFACE FACILITATED BY DIANTIPYRYLMETHANE IN THE PRESENCE OF EMULSIFIER OP

本文用循环伏安法研究了中性载体二安替比林甲烷(DAM)络合推动Dy(Ⅲ)在水/硝基苯(w/nb)界面的转移及其中性表面活性剂乳化剂OP对其电迁移过程的影响。提出了离子迁移的机理,确证了油相中载体DAM络合推动金属离子Dy(Ⅲ)在油/水界面的转移属于E机理,乳化剂OP在电荷转移反应中可起载体和相转移催化剂的作用。

The Dysprosium (Ⅲ ) transfer across the water/nitrobenzene (w/nb) interface facilitated by Diantipyrylmethane (DAM) in the presence of emulsifier OP has been studied by the cyclic voltammetry. The mechanism of the charge transfer reaction has been discussed. It has been concluded that the transfer process of Dy ion across w/nb interface facilitated by DAM is E mechanism and the emulsifier OP can participate in the charge transfer reaction as an ionophore and charge transfer catalyst.
