Abstract
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.
