摘要：

以TNT碱性废水(又称红水)为研究对象,采用钛基二氧化铅(dimensionallystableanodes)类阳极和不同材料的阴极对该类废水进行电化学处理。研究结果表明:不同的阴极材料、电流密度、pH值、槽电压、电解质浓度及极板间距对废水中COD_{Cr<\sub>的降解有不同程度的影响,并通过实验证实了电化学反应过程中苯胺类物质中间体的存在。}

Abstract:

The TNT (2,4,6 - trinitrotoluene) alkaline wastewater (red water) is st udied. PbO2/Ti electrode, as one of dimensionally stable anodes(DSA), and three kinds of cathodes have been employed in treating this kind of water. The results show that the cathode, electric current density, concentration of electrolyte, voltage, distance between the electrodes and pH have some extent of influence on the COD_{Cr<\sub> removal efficiency. In addition, the existence of the intermediate li ke aniline is proved up.}

Key words: 2 4 6 - trinitrotoluene wastewater, dimensionally stable anode, catho de deoxidization
