| 摘 要： | 采用盐酸改性的凹凸棒土(Att)为载体,制备负载锰氧化物的凹凸棒土复合材料,采用氮吸附比表面及孔结构分析、红外光谱、XRD等手段对酸改性凹凸棒土及其复合材料进行了表征。研究发现0.1mol/L盐酸处理的凹凸棒土的比表面积增加最明显;随负载氧化锰量的增大,比表面积和孔容下降;XRD测试表明,复合材料中氧化锰的主要成分是Mn3O4。

| Abstract: | Attapulgite modified with HCI used as supporter to synthesize attapulgite/manganese oxide composites, the composites were characterized with BET, 1R and XRD. Results showed that the surface area of the attapulgite treated with 0.1M HCI was improved obviously. The obtained attapulgite-manganese oxide composites mainly consist of Mn_3O_4. With increasing the amount of manganese oxide, surface area and pore volume decreased. |
