The Adsorptive Performance and Kinetics of Hemp Stem

Article Preview

In view of the unique porous structure of hemp stem, the comparison experiments were implemented on adsorption properties of hemp stem powder and Abies holophylla Maxim powder to formaldehyde, benzene and TVOC. In addition, on the basis of preliminary study on solid-gas adsorption kinetics of hemp stem, applicability of several adsorption theories was analyzed versus solid-gas adsorption. The results showed that the unique structure endowed hemp stem better adsorption properties than Abies holophylla Maxim’s. However, for different adsorbents, the adsorption kinetics characters differed obviously. Bangham and Langmuir adsorption rate equation fitted the gas-solid adsorption kinetics of hemp stem to some extent, and Langmuir’s could present its absorption to TVOC much better.
