Process and materials for cleansing areas affected by pollutants

摘要

A method for combating the emission of odorants and/or pollutants is described. The source of the odorants or pollutants is directly covered with a material containing adsorbent particles. An adsorbent material is also described which comprises a flat support material which forms a water-vapour permeable barrier layer and a layer located on said support material, containing adsorbent particles. A barrier layer covering the adsorbent particle-containing layer may be included. The coatings are used for decontamination of floors (eg by loading the back-side of a carpet with activated carbon spherules), walls and ceilings. The adsorbent material is preferably activated carbon or molecular sieves. Polychlorinated biphenyl is exemplified as a pollutant.
