摘　　要：研究了在没有及含有十二烷基苯磺酸钠 (SDBS)存在的 0 .1mol LNaHCO3底液中 ,铜 高铁试剂络合物的电化学行为。由于与十二烷基苯磺酸钠共吸附在电极表面上的超氧阴离子自由基氧化了电极反应中间体 ,产生了催化电流。The electrochemical behavior of Cu(II)-Ferron, both in the absence and in the presence of sodium dodecyl benzene sulfonate(SDBS) in the solution of 0.1 mol/L NaHCO3 was studied. Because SDBS and superoxide anion radical were adsorbed on the electrode surface, the reactive intermediate was oxidied by superoxide anion radical and the peak current of the complex was enhanced.
