Spherical beads of a hybrid-type ion-exchange (HIE) have been prepared by dispersing microcrystalline {lambda}-MnO{sub 2} in macroporous cellulose gel beads. The beads were 0.1 to 0.3 mm in diameter and contained 0.71 g {lambda}-MnO{sub 2}/g dry HIE. The ion-exchange behaviors of HIE for lithium and sodium ions were investigated by batch and column methods. The uptakes for lithium and sodium ions were 2.8 and 0.1 mmol/g dry HIE, respectively, at pH 12.3 by the batch method and 1.0 and 0.1 mmol/g dry HIE at pH 11.6-11.8, respectively, by the column method. When 1.52 L seawater was passed through a column containing 0.05 g wet HIE at a flow rate of 0.3 mL/min, 2.0 mg lithium/g dry HIE was recovered.
