采用经H2 O2和Ar/H2 O改性处理的生物炭处理高浓度含苯酚废水,以N2低温物理吸附和红外光谱技术对催化剂结构与性能之间的关系进行了研究。结果发现Ar/H2 O混合气体处理生物炭材料,可以降低材料表面酸性位的数目,显著增加材料表面的电子密度,可以有效促进H2 O2得电子生成羟基自由基,进而提高了苯酚的氧化分解速率。

In this paper, we treat of waste-water which contained high concentration of phenol by using H2 O2 and Ar/H2 O modified biochar. Cryogenic physical adsorption of N2 and infrared spectroscopy were used as studied the structure and properties of the catalyst. The results showed that the acid sites numbers of surface can be reduced by handling biological carbon materials which used the mixed gas of Ar/H2 O, so that the surface of the electron density of the material increases significantly and the process of H2 O2 obtained electronic to generate hydroxyl radicals was effectively promoted. Thereby it was increased the rate of oxidative decomposition of phenol.
