*3.7. Selective Adsorption on RCMs and RPMs*

The selectivity study of RCMs and RPMs was evaluated by using dencichine, two analogues including GL and GP, compared with the adsorption of dencichine in a single solution and the mixed solution (Table 3). Table 3 illustrated the data obtained from the selectivity experiment for both RCMs and RPMs, concerning the adsorption quantity.


**Table 3.** Preferential adsorption of dencichine on RCMs and RPMs.

In the single solution of three substances, the adsorption amount for dencichine on the RPMs and RCMs is 15.57 mg/g and 1.056 mg/g, respectively. The adsorption amount is better than those for the two analogues. Similarly, in the mixed solution of three substances, the adsorption amount for dencichine on the RPMs and RCMs was 13.79 mg/g and 0.8625 mg/g, respectively, which is significantly higher than those for the two analogues. This phenomenon illustrates a high discrimination property of RCMs and RPMs between dencichine and analogues. These results further proved the application prospect of RCMs in the separation of dencichine.
