Apr 22, 2020 The adsorption capacity of bentonite is substantial at low humidity levels and increases with increasing relative humidity. Silica gel behaves similarly, but becomes even more adsorbent at higher levels of relative humidity. At these higher humidity levels, its very high rate of adsorption can, at times, make silica gel more difficult to handle.
