摘　　要：煤矸石作为一种环境友好的吸附材料,因其离子交换性能和吸附性能被广泛用于环境净化。为了提高矸石基沸石对污染物的吸附性能,通过改性处理法,探索了矸石基沸石对不同微生物源有机碳单宁酸、果糖、球囊霉素相关蛋白和EPS的吸附能力。通过适当的预处理,获得纯化后的矸石基4A沸石,并对其进行多种有机物的吸附实验。通过SEM、FTIR分析吸附前后沸石的形貌变化和官能团变化,结果表明,吸附后材料的结构和化学性质发生了改变。吸附实验显示,沸石对于多种微生物源有机碳具有良好的吸附性,且吸附过程符合Freundlich吸附等温式,吸附剂表面呈非均质状态。因此,矸石基沸石是一种有效的吸附材料,适用于生态环境治理和土壤改良。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.
