The silicone has the open vesicular structure , large specific surface. So it can absorb many substances as a good desiccant, adsorbent and catalyst carrier. Adsorption of the silicone is mainly the physical one that can be regenerated and good for repeated use. Let the silica gel soak in the cobalt dichloride solution then get it dried and activated , will become the allochroic silica gel. It will transfer from blue to red color when absorb water.
