ABSTRACT:
Enzymatic dehalogenation of undesirable nitrogen-free organohalogen compounds is carried out by adding a dehalogenase to an aqueous composition comprising a nitrogen-free organohalogen compound and a nitrogen-containing cationic polymer. The enzymatic dehalogenation of the nitrogen-free organohalogen compound is achieved without any substantial effect upon the nitrogen-free organohalogen compound. The dehalogenation method may be carried out via continuous, batch, or semi-continuous processes.
