摘　　要：以自制的掺杂锰矿粉的β-PbO2/锰矿粉复合电极为阳极,不锈钢片为阴极对对硝基苯酚(p-NP)模拟废水进行了电解氧化处理。结果表明,掺杂适量锰矿粉的β-PbO2/锰矿粉复合电极具有良好催化氧化p-NP的性能,在以NaCl为电解质的体系中,电解效果明显高于其他电解质体系。在电解体系为弱碱性,电解质为10 g/L NaCl,电流密度为30 mA/cm2条件下,电解2 h后p-NP的去除率可达到99.43%。The p-nitrophenol-containing wastewater was electrolytically oxldated by using the stainless steel cathode and the manganese mineral-doped β-PbO2 anode. The result indicates that the manganese mineral-doped β-PhO2 anode had good performance in oxidating p-nitrophenol. In the system where NaCl was used as electrolyte, the effect of electrolysis was higher than other systems obviously. Under the conditions of the alkaline electrolyte and the current density of 30 mA/cm^2, approximately 99.43% of p-nitrophenol was degraded after 2 h.
