摘要：

During the adsorption of Pb, Cu, Mn or Zn by birnessite, 1 mol of H+ is released from the surface for each mole of metal ion sorbed. The potassium appearing in solution during adsorption is not directly involved in the reaction. This resolves some apparently conflicting published results. © 1979.
