ABSTRACT:
A process for the removal of aromatic compounds from aqueous solutions using an oxidatic enzyme, such as a peroxidase enzyme, is described. The enzyme is immobilized on a surface so that preferably multiple passes of the aqueous solution with the aromatic compound can be made over the immobilized enzyme. Higher enzyme utilization with a lower oxidative substrate, such as hydrogen peroxide, requirement is achieved.
