二氧化氯催化氧化降解水中苯酚的影响因素研究

Study on the Factors of Degradation of Phenol Aqueous Solution by Chlorine Dioxide Catalysis and Oxidation

使用自制二氧化氯和自制固体催化剂,催化氧化降解水溶液中苯酚,结果表明:固体催化剂用量,ClO2用量和溶液pH值是影响苯酚降解的主要因素,搅拌速度和溶液温度是次要因素。苯酚在室温酸性溶液条件下,ClO2和固体催化剂共同作用可被有效降解,有良好的工业应用前景。

The results of the degradation of phenol aqueous solution by using t he home-made Chlorine Dioxide and home-made solid catalysts indicate that the use level of chlorine dioxide and solid catalyst, the solution pH value are main factors influencing the degradation of phenol, and the mix speed and solution t emperature are secondary factors. Under the condition of room temperature and ac idic solution, phenol aqueous solution can be degraded by chlorine dioxide and s olid catalyst effectively. Chlorine dioxide catalysis and oxidation has good ind ustrial prospect in the treatment of wastewater containing phenol.
