Adsorption performance of gangue-based zeolite on different microbial sources of organic carbon in soil
As an environmentally friendly adsorbent material,gangue is widely used for environmental purification because of its ion exchange performance and adsorption performance.In order to improve the adsorption performance of gangue-based zeolite on pollutants,the study explored the adsorption capacity of gangue-based zeolite on different microbial sources of organic carbon tannins,fructose,balloonomycin-associated proteins,and EPS through the modified treatment method.The purified gangue-based 4A zeolite was obtained through appropriate pretreatment and subjected to adsorption experiments for a variety of organic compounds.The morphological changes and functional group changes of the zeolite before and after adsorption were analyzed by SEM and FTIR,and the results showed that the structure and chemical properties of the material were changed after adsorption.The adsorption experiments showed that the zeolite has good adsorption for many different microbial sources of organic carbon,and the adsorption process conforms to the Freundlich adsorption isotherm equation,indicating that the adsorbent surface is in a non-homogeneous state.Therefore,gangue-based zeolite is an effective adsorption material suitable for ecological environment treatment and soil improvement.
