✦ Synopsis

Once activated by hydrogen peroxide, horse-focused on the use of HRP because the enzyme is less radish peroxidase (HRP) catalyzes the oxidation of aquecostly to produce, inactivates less rapidly, or acts on a ous aromatic compounds to produce high molecular wider variety of substrates than other oxidoreductive weight polymers of low solubility. A pseudo steady-state enzymes (Nicell et al., 1993). Therefore, the HRP-catakinetic model of the HRP-hydrogen peroxide-aromatic lyzed process has potential applications in the treatment compound system was modified to incorporate enzyme of waters and wastewaters contaminated with phenoinactivation mechanisms in order to improve its predictive ability. The kinetic constants of the model were lic pollutants. calibrated using a series of experimental data sets. The Traditionally, steady-state models have been used to model's ability to predict the time-dependent removal of describe the function of the enzyme in its reaction enviphenol within the range of 0.5-6 mM from a batch reactor ronment. While such models may be used to evaluate was validated. The model accounts for permanent losses kinetic parameters of enzyme systems, they do not adeof enzyme activity through inactivation by free radicals as well as interaction with end-product polymers as they quately describe the reaction under nonideal and unform.
