Ionic exchange Behaviour of MnO2 and Selective Adsorption of Lithium Ions by MnO2 Ionic Sieve
Abstract:
Fibrous electrolytic manganese dioxide(EMD) was prepared from manganous chloride solution by electrolyzing at 90~95 ℃ and using graphite anode. EMD has the exchange properties with cations in aqueous chloride solutions. A lithium type ionic sieve made from EMD substrate may be used for selective adsorption of trace lithium from sea water with yield of about 90%.
