Study on Preparation of Acid Modified Attapulgite/manganese Oxide Composites

Gao Hua Li Cun Wu Zhenyu Liang Youling(School of Chemistry and Chemical Engineering,Anhui University,Hefei 230039)  
Attapulgite modified with HCl used as supporter to synthesize attapulgite/manganese oxide composites,the composites were characterized with BET,IR and XRD.Results showed that the surface area of the attapulgite treated with 0.1M HCl was improved obviously.The obtained attapulgite-manganese oxide composites mainly consist of Mn3O4.With increasing the amount of manganese oxide,surface area and pore volume decreased.
