| 摘 要： | 选择木素类模型物愈创木酚作为目标化合物,对UV/Fenton和Fenton体系降解愈创木酚的过程进行研究,结合愈创木酚紫外-可见光谱的变化、愈创木酚去除率和矿化率的比较,对UV/Fenton和Fenton体系降解愈创木酚的机理加以探讨.实验发现,UV/Fenton和Fenton体系不只是单纯的自由基反应,Fe2+还可以和H2 02生成高价铁配合物,通过配合物的电子转移使愈刨木酚得到氧化. |

| Abstract: | This paper selected guaiacol,one model compound of lignin,as the target compound to study the degradation of guaiacol by UV/Fenton and Fenton processes.With the help of guaiacol UV-visible spectrum changes,comparison of guaiacol removal rate and mineralization rate,the degradation mechanism of guaiacol by UV/Fenton and Fenton processes treatment was discussed.The experimental results showed that UV/Fenton and Fenton processes are not simply free radical reactions.Fe2+ and H2O2 can generate high iron complex... |
