A new method has been elaborated for the removal of phenols and aromatic amines from industrial waste waters. It involves the treatment of solutions containing the pollutants with horseradish peroxidase and hydrogen peroxide. Such treatment results in precipitation of phenols and aromatic amines from water due to their enzymatic crosslinking. This approach was used to remove over 40 different phenols and aromatic amines (including known human carcinogens and mutagens) from water. For many pollutants, the efficiencies of the enzymatic removal are very high (exceeding 99%), whereas for others they are significantly lower. It was discovered that easily removed phenols and aromatic amines greatly enhance the enzymatic precipitation of those that have relatively low removal efficiencies. This finding is of great importance for the treatment of real industrial wastewaters, which always contain mixtures of pollutants. The described method appears to be economically feasible and has been successfully employed for treatment of wastewaters obtained from a chemical plant.
