根据钨酸钠 /过钨酸钠氧化还原媒质催化 O2 在阴极电还原产生的 H2 O2 体系来间接氧化有机物的特点 ,对阴极间接电氧化体系 O2 电还原 H2 O2 的电流效率分别从 p H值、温度、电流密度、电量等因素进行最佳工艺条件的选择 ,从而得出最佳工艺条件 ,为进一步研究该体系打下基础 . According to the sodium tungstate / sodium peroxo-titanate redox catalyst in the cathodic reduction of H2 O2 generated by the system to indirectly oxidation of organic matter characteristics of the cathode indirect oxidation of oxygen O2 reduction of H2 O2 current efficiency from p H value, Temperature, current density, electricity and other factors to choose the best process conditions, so as to get the best process conditions, and lay the foundation for further study of the system.
