摘要 以二氧化铅为阳极,不锈钢网为阴极,用电化学氧化法处理多段漂白废水中的有害物质。其中二氧化铅电极是通过在碳棒上电镀而成的。研究发现,废水的电导率和pH值对于不同的废水在电化学氧化过程中的变化是不同的;而废水的COD和色度在整个过程中一直减少;氯化木质素的分子量和分子量分布发生了变化。 A kind of lead-dioxide electrode was prepared by plating lead dioxide on the surface of kryptol. Effluent from chlorine bleaching was disposed by electrochemical oxidation using PbO2 anode, stainless steel web cathode. The results showed that the COD and chroma of effluent decrease in the whole course of electrochemical oxidation. The change of pH value and electrical conductivity is different from different effluent. Aromatic rings of chlorinated lignin can cleavage during electrochemical oxidation. The molecular weight and distribution of the chlorolignin are also changed.
