Phenol from aqueous solution and removal manner null

摘要

PURPOSE:To suppress the adsorption of peroxidase as a catalyst on a phenol polymerization product and to reduce the consumption of peroxidase by adding a hydrophilic polymer to a liq. reactant. CONSTITUTION:Phenols and/or aromatic amines are allowed to react with hydrogen peroxide under the catalysis of peroxidase and removed from the aq. soln. Since a decrease in the activity of peroxidase is almost proportional to a decrease in the peroxidase itself, the deactivation of peroxidase can be explained only on the ground that peroxidase is adsorbed on the phenol polymerization product formed by the peroxidase removal reaction and removed from a liq. reactant. A hydrophilic polymer such as polyethylene glycol and PVA is effective in suppressing the adsorption of peroxidase.
