| Outline of Final Research Achievements |
Adsorption rates of some metal ions in the aqueous phase were measured by using the spherical mesoporous silica particles in the batch reactor. The adsorption rates can be correlated by the pseudo-second adsorption model, and the apparent diffusion coefficient in the mesoporous silica particles can be evaluated by the rate parameters in this model. This model can be also applied to the adsorption rate for metal ions with the spherical chelating agents and for the alcohol with ZIF-8. Furthermore, the breakthrough curves for the packed column of the adsorption process of metal ions with the spherical chelating agents can be evaluated with the pseudo-second adsorption model. We have been observed the overshoot phenomena for two metal ions by the packed column experiments. The quantitative calculation will be studied by the use of this model proposed in the study.
