实验研究了ＣｅＯ２ ·ｎＨ２Ｏ的表面特性，测定了ＣｅＯ２·０．６１Ｈ２Ｏ的表面电荷密度．依据溶液配位化学模型，求取了ＣｅＯ２·０．６１Ｈ２Ｏ颗粒表面配合反应的基本参数，并采用两种方法计算了其与Ｆ－ 的表面配合稳定常数．
The surface properties of CeO2 · nH2O were investigated experimentally and the surface charge density of CeO2 · 0.61H2O was measured. According to the solution coordination chemistry model, the basic parameters of the coordination reaction on the surface of CeO2 · 0.61H2O particles were obtained. The stability constants of the coordination with F- were calculated by two methods.
