摘要：

In a water-ethanol (50 v/v) medium, the presence of cationic (CTAB), anionic (SDS) or neutral (Brij-35 and Triton X-100) surfactants can modify the mechanisms of the electrochemical reduction of 4,4'-dinitrodibenzyl. The competition between the adsorption of substrate and surfactant molecules is studied. In the presence of neutral surfactants, the anion radical, generated by in situ electrolysis, is stabilized and its ESR spectrum can be obtained even at pH 7.
