Adsorption Precautions

⒈ When drying and regenerating, attention should be paid to gradually increase the temperature, so as not to cause the colloidal particles to burst due to severe drying and reduce the recovery rate.

⒉ When calcining and regenerating silica gel, too high temperature will cause changes in the pore structure of silica gel, which will obviously reduce its adsorption effect and affect the use value. For blue gel indicator or color-changing silica gel, the temperature of desorption and regeneration should not exceed 120 °C, otherwise the color developing effect will be lost due to the gradual oxidation of the color developer.

3. The regenerated silica gel should generally be sieved to remove fine particles to make the particles uniform.
