A model has been proposed for the interaction between the surface of metal oxide microparticle and divalent cation in aqueous solution. It is based on ideas as follows; zinc hydroxide is formed through bonding among Zn^<2+>, O^<2-> in OH and another Zn^<2+> in solution, and fixation of Zn^<2+> on the surface of metal oxide(alumina was mainly used) is brought through bonding among Al^<3+> in alumina, O^<2-> and Zn^<2+> in solution. Such fixation usually occurs at a certain pH below the pH region where zine hydroxide forms. Such change in pH is experimentally determined as pH. This can be related to the sterngth of the interaction between the surface of alumina and zine ion in terms 2.303RT pH. For many experimental systems pHs were determined. Many trials including electrophoresis measurements, codeposition of microparticles suspended in copper sulphate bath with copper, and stress corrosion of glass in aqueous solution were done in order to support the model.

提出了一个水溶液中金属氧化物微粒表面与二价阳离子相互作用的模型。其基本思想是：Zn^&lt;2+&gt;、OH中的O^<2->与溶液中的Zn ^&lt;2+&gt;成键形成氢氧化锌，而Zn^&lt;2+&gt;在金属氧化物（主要是氧化铝）表面的固定是通过氧化铝中的Al^&lt;3+&gt;、溶液中的O^<2->与Zn^&lt;2+&gt;成键实现的。这种固定通常在低于氢氧化锌形成的pH区域的一定pH下发生。这种pH值的变化在实验上被确定为pH值。这可以与氧化铝表面和锌离子之间的相互作用强度相关，以2.303RT pH值表示。对于许多实验系统，pH值被确定。许多试验，包括电泳测量，共沉积的微粒悬浮在硫酸铜浴与铜，玻璃在水溶液中的应力腐蚀，以支持该模型。
