What measures can be taken to improve the adsorption capacity and adsorption rate of adsorption resin?

In order to improve the adsorption capacity and adsorption rate of adsorption resin, the following measures can be taken:

1, the more polar molecules are suitable for separation on medium polar resin, and the less polar molecules are suitable for separation on nonpolar resin; For compound with larger volume, resin with lar pore size is selected;

2. Adding an appropriate amount of inorganic salts to the sample solution can increase the adsorption capacity of the resin; Acidic compounds are easily adsorbed in acidic solutions, alkaline compounds are easily adsorbed in alkaline solutions, and neutral compounds are easily adsorbed in neutral solutions. Generally speaking, the lower the concentration of the sample solution, the better the adsorption; For the choice of dropping speed, it is better to ensure that the resin can fully contact and adsorb with the sample solution.
