Powdered Activated Carbon – PAC
Powdered activated carbon (PAC) is a form of highly porous carbon material with a particle size typically between 10 and 100 µm.
primarily used for its exceptional ability to adsorb a wide range of organic compounds and impurities from liquids and gases. Its fine particle size allows for fast adsorption kinetics and a high surface area.
Common Applications
Powdered activated carbon is used across various industries, from environmental applications to health and beauty products.
- Water Purification: Municipal water treatment plants use PAC to remove contaminants, such as algal toxins, pesticides, industrial chemicals, and unpleasant tastes and odors, from drinking water.
- Industrial Processes: It is used for treating refinery, petrochemical, pharmaceutical, and other industrial wastewaters to remove persistent organic compounds and heavy metals like mercury.
- Food and Beverage Industry: PAC is used in the decolorization and purification of food liquids, syrups, edible oils, and beverages, including wine and alcohol, to remove unwanted colors, haze, and odors.
- Medical and Pharmaceutical Use: It is a key ingredient in pharmaceutical purification processes (e.g., antibiotics, steroids) and is used in emergency rooms as an antidote for certain types of poisoning or drug overdoses to absorb toxins in the digestive system.
- Cosmetic and Personal Care Products: Due to its detoxifying properties, activated charcoal powder is a popular ingredient in DIY cosmetic preparations such as face masks, shampoos, and toothpaste for removing impurities and whitening teeth.
