1、Desiccant: One of the most common uses of silica gel is as a desiccant. Due to its excellent moisture absorption properties, it is widely used to protect products from moisture, especially in electronics, food packaging, and pharmaceutical packaging.
2、Drug Carrier and Delivery: Silica gel is also used in drug delivery systems. By adjusting the pore size and surface properties, silica gel can serve as a drug carrier for controlled-release formulations. This is particularly useful for chronic diseases where sustained drug release is desired.
3、Air and Water Treatment: Silica gel is used in air and water purification processes due to its ability to adsorb harmful gases and pollutants such as carbon dioxide and ammonia. It is also employed in water treatment to remove organic contaminants.
