| 摘 要： | 苯胺的超临界水氧化表明,氧化剂Ｈ２Ｏ２、试验温度、压力和停留时间以及水样的起始ＴＯＣ值对ＴＯＣ的去除率有显著影响．在本试验中,选取了硫酸铜、硫酸铁、硫酸锰等金属盐进行苯胺的均相催化氧化试验研究,结果表明,这些金属盐对苯胺的氧化有不同的催化活性,筛选出硫酸锰和和硫酸亚铁进行了进一步的研究．以硫酸锰作催化剂为例,在４５０℃,２８ＭＰａ,Ｋ＝１．１,ｐＨ＝４．０的条件下,当停留时间为４６ｓ时,ＴＯＣ去除率达到１００%．

| Abstract: | The oxidation of aniline in supercritical water indicated that the dosage of the oxidant H2O2,experimental temperature,pressure,reaction residence time and even initial concentration of theaniline in wastewater have remarkable effect to the TOC removal.Various metal salts,for examplecopper sulphate,copper nitrate,ferric and ferrous sulphate,ferric chloride,manganous sulphateand vanadium pentoxide,as catalysts have been selected to study the catalysis oxidation of aniline.The results show that the metal salts have respective catalysis activities to the oxidation of aniline inthe homogeneous phase reaction system.Two metal salts have been screened for further study. |
