A method of removing pollutants from building materials using an externally applied adsorbent. The adsorbent has a high affinity to common pollutant chemicals. The pollutants are transferred from the contaminated microporous building materials onto the adsorbent until sufficient amounts of pollutant chemicals are reduced to make the building materials acceptable and safe to use. The adsorbent may be regenerated and reused or treated as a waste.

Adsorbent mediated reduction of organic chemicals from solid building materials

A method, using a photocatalyst, to accelerate the reduction of semivolatile organic chemicals absorbed into porous, solid materials. The porous, solid material having absorbed one or more semivolatile organic contaminants. The photocatalytic material located on the surface of the porous, solid material is exposed to a light source, under aerobic conditions, which excites the photocatalyst and results in the reduction of the absorbed semivolatile organic chemical contaminants.

Photocatalyst-induced reduction of semivolatile organic chemicals absorbed in solid materials

A method of removing pollutants from porous, solid materials uses a biomass loaded onto a support. The biomass is put into contact with a pollutant contaminated porous, solid material so that the bacterial biomass degrades the pollutant. The moisture level of the support and biomass are maintained at a level that optimizes pollutant removal and is a function of the relative solubility of the pollutant.
