A study on adsorption properties of Zhejiang diatomites

Keywords： Zhejiang diatomite , pore structure , adsorption isotherm

测定了25℃时浙江硅藻土对苯的吸附等温线及吸附回线,硅藻土的孔径分布、硅藻土表面硅羟基SiOH数目,并讨论了吸附等温线及吸附回线与孔结构、表面SiOH数目之间的关系.

In this paper, benzene adsorption isotherm and their hysteresis on Zhejiang diatomite was determined at 25℃, and its pore-size distribution, and silicon hydroxyl groups (SiOH) number per nanometer square (nm2) was determined, the relationship between pore structure, surface SiOH number and adsorption isotherm with hysteresis was discussed.
