摘　　要： 采用紫外光/高铁酸盐协同方法对水中苯酚的氧化去除进行了研究,并将紫外光/高铁酸盐协同方法与单纯的高铁酸盐氧化法进行了对比,对影响苯酚去除率的溶液pH、高铁酸盐用量等因素进行了考察.结果表明,紫外光/高铁酸盐协同方法明显优于单纯的高铁酸盐氧化法,苯酚的去除率随溶液pH降低、高铁酸盐用量增加而不断升高;在紫外光照射、溶液pH=4、高铁酸盐质量浓度为30 mg.L-1的条件下,水中苯酚的去除率可达到90%左右,与单纯高铁酸盐氧化相比,苯酚的去除率提高近30%. The phenol removal by the cooperation action of UV/sodium ferrate,compared with potassium ferrate was investigated,and the factors of pH,potassium ferrate dose on the removal of phenol were researched.The results showed that the phenol removal ratios of the cooperation action were prior to that of potassium ferrate and that the phenol removal ratios raised if there were lower pH,more potassium ferrate dose and that when the potassium ferrate concentration was 30 mg·L^(-1) with UV and pH=4,the phenol removal...
