Preparation of mesoporous MnO2/SBA-15 and its cesium ion adsorption properties

Mesoporous MnO 2 /SBA-15 was prepared by a facile route using KMnO 4 and MnCl 2 as Mn source and used for removal of Cs + . The effects of MnO 2 content, initial Cs + concentration, contact time and pH on the Cs + adsorption behavior were investigated. It was found that Cs + adsorption capacity of S...

Summary:Mesoporous MnO 2 /SBA-15 was prepared by a facile route using KMnO 4 and MnCl 2 as Mn source and used for removal of Cs + . The effects of MnO 2 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 MnO 2 loading. The adsorption capacity increased with increasing MnO 2 content. Furthermore, the adsorption data can be well fitted by the Langmuir model, and the calculated maximum adsorption capacity of 80%MnO 2 /SBA-15 is 104.8 mg/g. The Cs + adsorption process can be better described by the pseudo-second-order model.
