How do silica gel works in adsorption column chromatography?
The use of silica gel can be interpreted in two ways. It well know that silica (SiO2) can adsorb water on its surface. If you use silica dryed under 400 °C, the process of adsorption occurs by the silanol group. So, molecules with a polar groups like hydroxil, amine, nitrilic ... can make chemical interactions with the silica surface and can be retained more time into a column. In this case the adsorption is chemical. But, if you use a deactived silica (~5% H2O), the H2O molecules make a layer into a silica surface and the main process occurs by partition chromatography.
In organic gardening is silica gel in packets safe to recycle into compost pile for flower and vegetable gardens?
While it isn't unsafe to compost Silica Gel, it will not decompose. The Silica Gel will simply absorb moisture from the compost until it is completely saturated. Silica Gel is useful for drying and preserving seeds and therefore can be useful for organic gardening.
