已发现水悬浮液中亚锰酸锰 (II) 上 I 族和 II 族阳离子的吸附在低浓度下强烈依赖于 pH，但在较高浓度下与 pH 无关。在稀溶液中，吸附必须作为扩散双层中的抗衡离子发生，而较高浓度下的广泛吸收表明这些离子被纳入锰酸盐晶格的无序层中。此外，过渡金属离子的吸附研究表明，Ni2+、Cu2+，尤其是 Co+2 表现出显着的特异性吸附，这些离子在零电荷点的有限吸附证明了这一点。
The adsorption of Groups I and II cations on manganese (II) manganite in aqueous suspension has been found to be strongly dependent on pH at low concentrations but is independent of pH at higher concentrations. In dilute solution, adsorption must then occur as counter ions in the diffuse double layer, whereas the extensive uptake at higher concentrations indicates that these ions are incorporated into the disordered layer of the manganite lattice. In addition, adsorption studies with the transition metal ions show that Ni2+, Cu2+and especially Co+2exhibit marked specific adsorption as evidenced by the finite adsorption of these ions at the zero-point-of-charge.
