摘要
利用紫外可见光谱和高效液相色谱研究了催化氧化降解苯酚的过程.结果表明,非晶铁氧化物催化剂在催化氧化降解苯酚时具有较高的催化活性,苯酚降解的中间产物有:对苯二酚、邻苯二酚、苯醌和低级脂肪酸,其降解机理是羟基自由基攻击苯环上OH的邻位或对位而使苯环开环,生成低级脂肪酸,并最终转化成二氧化碳和水,从而使苯酚得以降解.
The process of Phenol Catalysis-Oxidation Degradation was studied with UV spectrum and HPLC. The results showed that the amorphous iron oxide has highly catalytic activity. The intermediate products are pyrocatechin, hy＇droquinone, benzoquinone and low-grade fatty acid. The mechanism of catalyst oxidation is assumed that the free radical OH attacks benzene cycle at the adjacent position and para-position of OH on phenol so that the benzene cycle is opened and low-grade fatty acid is produced and transformed into CO2 and H2O.
