This study synthesized a phenolic microsphere lithium manganese oxide (LMO) adsorbent by the polycondensation method and prepared a microsphere LMO microsphere adsorbent with a spinel structure by the carbonization method. The structure of the microsphere LMO precursor was confirmed, and the crystalline structure, compressive strength, BET surface area, morphology, and acid resistance of the porous adsorbent were analyzed by BET surface area, UTM and XRD. The adsorbent was stable against acid due to its cross-linked structure. In pure solution, the breakthrough of lithium was at over 8 hours, which was more rapid than the with LMO powder adsorbent. |
