| 摘 要： | 通过微波辐射前后水样的紫外分光扫描分析，以及微波辐射后水样中的苯酚浓度和COD浓度之间线性相关性分析表明，活性炭-微波辐射强化除酚效率的主要机理是微波使反应体系温度升高导致的活性炭加速吸附作用，而不是微波诱导催化氧化作用。通过对微波辐射前后活性炭的SEM扫描电镜分析说明，活性炭在微波场中由于“微域爆炸”导致其表面及内部孔隙结构的变化， 吸附性能得到改善，是强化苯酚去除的另一原因。 研究还表明，在较短的作用时间内，活性炭-微波辐射法的除酚效率高于常温吸附，但低于沸腾条件下的高温吸附。活性炭-微波辐射去除苯酚的规律遵循其吸附特性，温度越高，吸附反应速度越快。

| Abstract: | The wastewater samples being irradiated by microwave or not had been scanned by ultraviolet spectrophotometer,and the linear relationship between the concentration of COD and phenol in the wastewater sample irradiated by microwave had been analyzed.The results show that the main mechanism of strengthening removal efficiency of phenol in the process of activated carbon-microwave irradiation is accelerating adsorption of activated carbon because of the raising temperature caused by microwave irradiation,and i... |
