| 摘 要： | 利用3，6-二氧杂-1，8-辛二硫醇（H2L）和HgCl2反应，得到组成为Hg3L2Cl2的配合物。制备了Hg3L2Cl2修饰的碳糊电极，研究了在1mol／L KCl水溶液中的循环伏安行为。研究结果表明在1mol／L KCl介质中，在0．3～-0．8V（vs．SCE）范围内出现Hg3L2Cl2的还原和L^2-在汞膜表面的吸附，在一0．30—0．30V范围内出现汞膜的氧化还原反应。

| Abstract: | A kind of insoluble complex,Hg_3L_2Cl_2,which was confirmed by element analysis and IR,was synthesized using 3,6-dioxa-1,8-octanedithiol(H_2L) and HgCl_2.The chemically modified carbon paste electrode with Hg_3L_2Cl_2 was prepared and its cyclic voltammetry behavior was studied in aqueous 1 mol/L KCl supporting electrolyte.There were two reduction peaks and three oxidation peaks in the potential range of 0.3 V to-0.8 V(vs.SCE).The reduction peak of Hg_3L_2Cl_2 is at-0.688 V(vs.SCE),with the oxidation peak is at-0.650 V(vs.SCE). |
