| 目的 评估改性煤矸石对污水处理的应用价值。方法 利用酸和碱分别对煤矸石进行改性,通过热重分析、X射线衍射分析和N2吸附等手段对煤矸石和改性煤矸石的比表面积和吸附能力进行了比较。结果 改性煤矸石具有较大的比表面积(172.4 m2/g),对原油的吸附能力增强。结论 改性煤矸石具有良好的吸附能力,为作为一种新型的吸附剂处理污水。 |

| Objective To investigate the application value of the evaluation of modified coal gangue for sewage treatment.Methods Modified coal gangue was modified using acid and alkali,respectively.The specific surface area and absorption capacity between coal gangue and modified coal gangue were compared by thermogravimetric analysis(TGA),X-ray diffraction(XRD) analysis and N2 adsorption.Results The absorption of oil in sewage by modified coal gangue was studied.The experimental results showed that modified coal gangue had a larger specific surface area of 172.4 m2/g and its absorption capacity of crude oil was increased.Conclusion The modified coal gangue has a good adsorption capacity for sewage treatment,which provides a new adsorbent. |
