苯酚模拟废水的新型处理材料——新生态—二氧化锰的合成与表征

Adsorption of Phenol by the Material——the Nascent Manganese Dioxide(NMD) and its Characterizations

以苯酚模拟废水为吸附质,实验不同方法合成的二氧化锰对苯酚的吸附性能,选择其中合成简便、吸附效果优良的称之为新生态MnO2,并对其进行表征。结果表明:新生态MnO2为准球形的δ-MnO2颗粒,其颗粒比表面积325m2/g,对苯酚的吸附效果优良,表面富羟基。

In this research, the synthesis of manganese dioxide （MD） by 12 different methods were stuied, and the nascent manganese dioxide （NMD） as the new material was characterized in the detail. The experimental results showed that the NMD has high adsorption of phenol and it was δ-WnO2 with quasi-spherical shape , surface area 325 m^2/g.
