摘要：
Mesoporous MnO2/SBA-15 was prepared by a facile route using KMnO4 and MnCl2 as Mn source and used for removal of Cs+. The effects of MnO2 content, initial Cs+ concentration, contact time and pH on the Cs+ adsorption behavior were investigated. It was found that Cs+ adsorption capacity of SBA-15 can be significantly improved by MnO2 loading. The adsorption capacity increased with increasing MnO2 content. Furthermore, the adsorption data can be well fitted by the Langmuir model, and the calculated maximum adsorption capacity of 80%MnO2/SBA-15 is 104.8 mg/g. The Cs+ adsorption process can be better described by the pseudo-second-order model.
