Microscopic Structure and Adsorption Properties of the Terpenoids-Based Adsorption Material

Abstract

In this paper, a new type of natural adsorption materials were prepared by spray granulation. The structure and properties of the product were characterized by scanning electron microscope analysis, N2 adsorption desorption analysis, infrared analysis, X ray diffraction analysis, the rmogravimetric analysis. The results showed that: the best preparation conditions of the adsorption materials were as follows: the temperature was 59.21°C, the pressure was 0.28 Bar, and the rate was 14.15 ml/min. In addition, the natural materials had high porosity and specific surface areas , which was better for adsorption. The pore size was mainly concentrated between 13 ~ 28nm. Moreover, these materials had more functional groups. The decomposition temperature was 250°C,which resulted in better thermal stability. Consequently, the materials had better adsorption properties, and the materials will have better application prospect.
