Removal of 4-chlorophenol by soybean peroxidase and hydrogen peroxide in a discontinuous tank reactor
چکیده انگلیسی

A discontinuous tank reactor was used to eliminate 4-chlorophenol using soybean peroxidase (SBP) and hydrogen peroxide in an attempt to reduce the concentrations of buffer solutions used and to avoid adding polyethylene glycol. The stirred-tank reactor was operated in different operating conditions, and the influence of enzyme and substrate concentrations on the elimination of 4-chlorophenol was determined. Most of the assays provided good elimination percentages, which reached almost 90% for an enzyme concentration of 7.5·10–3 mg cm–3 and a stoichiometric ratio of 1:1 for both substrates, when concentrations of 1.5 mmol dm–3 or less were used. This work is a first step in the study of the SBP/4-chlorophenol system in order to observe the influence of the reagents concentrations when no polyethylene glycol is added.
