本文从Crank关于扩散-吸附过程的动力学关系式出发,得出了便于应用的动力学关系式并进而导出浸渍深度的计算公式.从所导出的关系式可以解释文献中关于浸渍深度的实验规律.由H_2PtCl_6溶液浸渍η-Al_2O_3小球的实验表明,浸渍深度的计算值与实验值是符合的.
Based on Crank’s kinetic relation of diffusion-adsorption process, the kinetic relation for easy application and the calculation formula of impregnation depth are deduced.Experimental rules about impregnation depth in the literature can be explained from the derived relations The experiment of impregnating η-Al 2 O 3 spheres with H 2 PtCl 6 solution showed that the calculated value of impregnation depth was in good agreement with the experimental data.
