摘要
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 feature of CeO 2·nH 2O were investigated through the agency of TGA,XRD and IR analysis of samples.The surface charge density of CeO 2·0.61H 2O was determined by acid base titration,and the intrinsic ionization constants were calculated on the ground of the surface complexation model.Two methods were applied to calculate the binding constants of the surface complexation of fluoride ions on hydrous ceria.
