What Is Activated Charcoal Powder?
Powdered activated carbon is a finely ground form of activated carbon, with a particle size generally less than 0.177 mm (80 mesh). This material is characterized by its enormous surface area and high adsorption capacity, making it an extremely effective adsorbent for a wide range of contaminants.
Powdered activated carbon can be produced from a variety of raw materials, such as coconut shells, charcoal, wood and other organic materials. The activation process involves heat treatment of these raw materials under anaerobic conditions, followed by physical or chemical activation that creates a complex porous structure.
One of the most outstanding features of powdered activated carbon is its immense internal surface area, which can reach up to 1500 m²/g. This vast area, together with its microporous structure, allows it to effectively capture molecules of various sizes, from organic compounds to heavy metals.

Factores que Influyen en la Dosificación
- Concentración inicial de contaminantes: Cuanto mayor sea la concentración, mayor será la dosis necesaria de carbón activado en polvo.
- Tiempo de contacto disponible: Un tiempo de contacto más corto puede requerir una dosis mayor o un carbón activado en polvo de malla más fina para compensar.
- Temperatura del medio: Las temperaturas más bajas reducen la cinética de adsorción; puede ser necesario ajustar la dosis.
- pH del medio: Esto afecta a la carga superficial del carbón activado en polvo y a la ionización de los contaminantes, lo que influye en la eficiencia de la adsorción.
- Presencia de competidores: Otros compuestos orgánicos pueden competir por los sitios de adsorción, lo que requiere dosis adicionales.
- Calidad: El carbón activado en polvo con un índice de yodo y una superficie específica más altos puede requerir dosis más bajas para el mismo nivel de tratamiento.
