| 摘 要： | 以粉煤灰为原料，采用两步水热法制备人工沸石。SEM、XRD、X射线荧光光谱分析结果表明:制得的人工沸石纯度较高，主要为Na-A型沸石和少量13X型沸石，主要化学成分为SiO2和Al2O3。说明采用两步法制备人工沸石克服了传统水热法杂质含量高的缺陷。采用人工沸石处理初始Mn2+质量浓度为50.00mg/L的模拟含锰废水，吸附125min后，Mn2+去除率达98.19%，模拟废水中剩余Mn2+质量浓度为0.90mg/L。

| Abstract: | Artificial zeolite was prepared by two-step hydrothermal method using fly ash as raw material. The analysis results of SEM,XRD and X-ray fluorescence spectrometry show that:The artificial zeolite product is pure,its structure is mainly Na-A type and a few 13X type,its major chemical compositions are SiO2 and Al2O3. This indicates that the two-step hydrothermal method can overcome the shortcomings of traditional hydrothermal method with lots of impurities. The simulated wastewater with 50.00 mg/L of Mn2+ mass concentration was treated with the artificial zeolite product. After 125 min of adsorption,the Mn2+ removal rate is 98.19% and the mass concentration of Mn2+ in the treated wastewater is 0.90 mg/L. |
