Potassium Permanganate Activated Carbon

Potassium permanganate impregnated activated carbon is a kind of high quality active carbon filter material, which is made by uniform deposition of KMnO (KOH) on the surface and pore net of high quality active carbon. The dipping method includes a controlled wet chemical treatment to assure an even distribution of potassium permanganate over the interior of the carbon at optimal loading concentrations. Careful drying and conditioning of the resultant product is carried out in such a way as to maintain the oxidation activity of the permanganate as well as the absorption integrity of the lower carbon matrix.

What distinguishes KMnMO from traditional PAC is the fact that it combines two separate pollution-removing mechanisms at the same time. The standard active carbon is used to get rid of contaminants by means of physical absorption – by means of a van der Waals force to capture molecules on the inner surface of the plant. Potassium permanganate gives rise to a strong process of chemical oxidation: KMnO is a potent oxidant which can directly interact with the reductant and VOC and decompose it into non-hazardous by-products or in a form which can be easily stored on the carbon substrate. The synergistic effect of oxidation and absorption confers on activated carbon, which is saturated with potassium permanganate, its characteristic advantage in removal of hydrogen sulphide (H ₂ S), formaldehyde (HCHO), ethylene, ammonia, and other chemical reactions that only physical absorption can do badly.
