摘　　要：综述了不同高级氧化技术降解有机膦酸的研究进展,有机膦酸自身基团种类及数目、水中共存离子及有机物对有机膦酸的降解产生显著的影响;其可被自由基攻击降解,亦可通过分子内电子转移过程被去除,和自由基机制比较,分子内电子转移过程受水体基质干扰更小,在实际废水处理中具有更优异的降解有机膦酸的性能。自由基和非自由基机制下有机膦酸的降解具有类似的氧化机制,均通过C—N或C—P键的断裂实现有机膦酸的降解。提出今后研究的重点应该为实际废水中有机膦酸形态特性分析、降解机制的多样性及普适性探究、磷的回收及工程应用。The research status of phosphonate removal by different advanced oxidation processes is reviewed.The type and number of groups in phosphonate,coexisting ions and organic matters in water show significant effects on the degradation of phosphonate.Phosphonate could be degraded by free radical process and intramolecular electron transfer process.Compared to the free radical mechanism,intramolecular electron transfer process is less disturbed by water matrix,which shows better performance of phosphonate removal in actual wastewater treatment.The free radical mechanism and the nonradical mechanism have a similar oxidative mechanism for the degradation of phosphonate,which is removed via the cleavage of C-N or C-P bond in both processes.It is suggested the further studies should focus on the analysis of the morphological characteristics of the phosphonates in actual wastewater,the diversity and universality of degradation mechanism,phosphorus recovery and engineering application.
