Ball Milling Mno2

It qualifies AGMnO2 for superior adsorption capability for heavy-metal ions after in situ loading of MnO2. High-energy ball milling preparation takes 6 h at the speed of 600 rpm, which increases the adsorption capacity from 4.88 to 135.81 mgg. The removal of CdII by AGMnO2 is mainly by electrostatic attraction.
