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

摘要

In this paper, a new type of natural adsorption materials was prepared by spray granulation. The structure and properties of the product were characterized by scanning electron microscope analysis, N_2 adsorption desorption analysis, infrared analysis, X ray diffraction analysis, the rmo-gravimetric 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.
