A new enzymatic process for the treatment of phenolic pollutants

Abstract

This work aimed to develop a new economic enzymatic process to treat the phenolic pollutants using pure tyrosinase in stirred vessel and adopting temperature (T), pH, rotational speed (N), initial phenol (C P,o ) and enzyme (C T ) concentrations as independent variables. Experimental data of the residual phenol concentration (C P ) were used to calculate the oxidation efficiency (η), initial oxidation rate (-r o ) and time required to reach the end of reaction (t) that were selected as the responses. Under the optimal conditions (T = 45°C, pH 6.6
