ABSTRACT:
A method is disclosed for removing organic substances, such as phenols and aromatic amines, from aqueous solutions by adding chemicals, such as peroxidase enzymes and peroxide substrates, to such solutions. A surprising discovery is that the presence of more than one organic substance greatly increases the efficiency of precipitation of substances that do not precipitate efficiently in the absence of other organic substances.
