一个表面络合模型被用来描述镱和铯在二氧化硅表面上的吸附。恒定电容模型给出了这项工作所选择的固溶体界面的描述。建模的第一步是提取表面酸性常数。结果是:第二步包括提取镱和铯的表面络合常数。阳离子的吸附如下所示:对于镱吸附,对于铯吸附,在铯的情况下,钠的吸附是竞争性的,必须考虑:版权所有1999学术出版社。
A surface complexation model is used to describe sorption of ytterbium and cesium on the silica surface. The constant capacitance model gives the description of the solid-solution interface chosen for this work. The first step in the modeling consists of extracting the surface acidity constants. The result is: The second step consists of the extraction of surface complexation constants for both ytterbium and cesium. The sorption of the cations is represented as follows: for the ytterbium sorption, for the cesium sorption, In the case of cesium, the sorption of sodium is competitive and has to be considered: Copyright 1999 Academic Press.
