Abstract

The results of 4-aminopyrimidine (4-APM) impact studies on the double layer parameters at the R-AgLAFE/ chlorates(VII) interface in the solutions with different water activity as well as different properties of the mixed adsorption layer of 4-aminopirimidine – sodium 1-decanesulfonate (SDS) and 4- aminopyrimidine - hexadecyltrimethylammonium bromide (CTAB) at the electrode/solution interface are discussed.The differential capacity of the double layer (Cd) at the R-AgLAFE/ basic solution interface was measured using the electrochemical impedance spectroscopy. The zero charge potential (Ez) was determined using a streaming electrode, while the surface tension at the zero charge potential (Yz) was measured using the largest pressure method inside the mercury drop. It was proved that both the 4-aminopirymidine concentration and water activity have an essential effect on the doublelayer parameters on the R-AgLAFE/ chlorates(VII) interface. In the studied systems: 4-APM - SDS and 4-APM - CTAB, 4-aminopyrimidine dominance was observed.

4-氨基嘧啶在R-AgLAFE/氯酸盐界面上的吸附比较不同水活度及不同表面活性剂的吸附性能

4-氨基嘧啶（4-APM）对不同水活度溶液中R-AgLAFE/氯酸盐（VII）界面双层参数的影响研究以及电极/溶液界面上4-氨基嘧啶-1-癸磺酸钠（SDS）和4-氨基嘧啶十六烷基三甲基溴化铵（CTAB）混合吸附层的不同性质进行了讨论。使用电化学阻抗谱测量了R-AgLAFE/碱性溶液界面处的双层（Cd）的微分容量。使用流动电极测定零电荷电势（Ez），同时使用汞滴内部的最大压力法测量零电荷电势下的表面张力（Yz）。结果表明，4-氨基吡里脒的浓度和水活性对R-AgLAFE/氯酸盐（VII）界面上的双层参数都有重要影响。在所研究的4-APM-SDS和4-APM-CTAB体系中，观察到4-氨基嘧啶的优势。
