以1.0g苯酚溶于1000mL无酚水中作为模拟水样组成反应模型,利用微波辐射以Fenton试剂与活性炭组成的催化氧化体系来降解水中苯酚,并研究了各种因素对微波辐射该体系催化氧化降解苯酚反应的影响.研究表明,微波辐射Fenton试剂-活性炭催化氧化体系能高效快速降解水中苯酚,较彻底地矿化水中有机物,使处理后的模拟水有机物含量达到饮用水的标准.其优化条件为:微波输出功率650W,微波辐射时间为15min,活性炭用量1.0g,Fenton试剂H2O2与FeSO4.7H2O物质量比为50∶1.

The waste water model is composed of 1.0 g phenol in 1 000 ml solution,and phenol is degraded in the system of Fenton reagent-activated charcoal under microwave radiation.The effect in different factors on the degradation of phenol was studied.The results showed that the phenol was degraded rapidly and high efficiently in the system of Fenton reagent-activated charcoal under microwave radiation,and that the optimum conditions are as follows:the microwave radiation power input is 650 W;the time of microwave radiation,15 min;activated charcoal mass 1.0 g;the molar ratio of H_2O_2 and FeSO_4,50∶1.
