Abstract
A method for the selective separation of a particular compound from a mixture of compounds, by enzymatically converting a weakly adsorbable compound to a strongly adsorbable compound, and binding the converted compound to a material of appropriate chemical properties is described. Also described are methods for removing contaminants from wastewater streams, and from intermediate chemical process streams.
