WebHow is silica gel regenerated ? Self-indicating silica gels when they have become saturated can be regenerated by heating at 100 - 120°C until they return to their original colours. The heating literally drives off the adsorbed moisture. Regeneration can be carried out repeatedly, although eventually the crystals will lose their colour. WebSilica gel's high surface area (around 800 m²/g) allows it to adsorb water readily, making it useful as a desiccant (drying agent). Once saturated with water, the gel can be regenerated by heating to 120 °C (250 °F) for two hours. Some types of silica gel will "pop" when exposed to enough water. Preparation.

Regular density silica gel is prepared in an acid medium and has a high surface area (e.g., 750 m 2 g −1). Intermediate and low density silica gels have low surface areas (300–350 and 100–200 m 2 g −1, respectively). brahmastra hd torrent
