随着污泥数量和处理量的增加,人们的关注度越来越高,特别是对于环境友好和高附加值的再利用需求尤为突出。为此,以磁性多孔污泥炭(MPC)作为新型催化剂,对过硫酸盐存在下四环素的催化氧化过程进行了研究。结果表明,MPC在活化过硫酸盐和产生活性氧自由基(SO_4~-·和·OH)方面具有强大的催化活性,在初始pH为10时,降解270 min后,四环素和总有机碳的清除率达到89%和70.5%。不同起始pH下的降解动力学实验表明,四环素降解过程是pH依赖型的,碱性环境条件有利于降解的发生。

With the increasing concern of the rapid production and disposal of sewage sludge, the need to develop more environmental-friendly and high value-added benign re-use of sewage is of particular importance.In this study, sewage sludge derived magnetic carbon was fabricated and used as a novel catalyst for catalytic oxidation of Tetracycline（TC） in the presence of persulfate（PS）. The results showed that magnetic porous carbon（MPC）exhibited superior catalytic activity to activate persulfate and generate more powerful reactive oxygen species（...
