银媒介间接电化学氧化（A g/M EO ）技术是一种有机溶剂分解破坏的有效方法。本文采用小型氧化电解池和新鲜磷酸三异戊酯（TiAP）有机溶剂模拟研究了在含 Ag＋的 HNO3溶液体系中氧化分解TiAP ，包括电解氧化过程中阳极室 HNO3浓度、操作温度等条件对Ag2＋产生量的影响，以及影响Ag2＋氧化分解TiAP有机溶剂的相关因素。研究结果表明，溶液中Ag＋和HNO3浓度的提高有利于Ag2＋的生成；操作温度的升高，不利于Ag2＋的生成。最佳条件为：温度，40℃；HNO3浓度，8 mol/L；电流密度，0.5 A/cm2。在此条件下，8 h可将99.9％的T iA P氧化分解。

A silver mediated electrochemical oxidation is a promising technique for the destruction of organic compounds .The destruction of spent organic solvent in nitric acid medium containing Ag + was studied by using a laboratory scale electrochemical oxidation cell and fresh 30% tri-isoamyl phosphate (TiAP) .The factors affecting the generation of Ag2 + and its capability to decompose TiAP were investigated , which include temperature , nitric acid concentration and current density . T he results show that the generation of Ag2+ increases with the concentrations of HNO3 and Ag+ and reduces with the increase of temperature .It is also found that the destruction rate of TiAP is 99.9% with a temperature of 40 ℃ ,a nitric acid concentration of 8 mol/L ,and a current density of 0.5 A/cm2 for 8 h .
