study of degradation of btex aromatic compounds using peroxidase enzymes

Today, water resources conservation is considered as the most vital human resource by various international communities# the water stream is mainly contaminated by the various applications# due to the low efficiency and issues of conventional treatment methods, newer methods of treatment of industrial wastewater are being introduced# one of the new methods is the use of peroxidase enzymes in the treatment of industrial and urban wastewater# in this paper, four different peroxidase enzymes have been studied to remove btex compounds (benzene, toluene, ethylbenzene, and xylene) in wastewater effluent# the best peroxidase enzymes have been chosen to decrease btex compounds after evaluating the four enzymes via the hierarchical analysis process (ahp)# the cost, efficiency, environmental requirements, and industrialization have been selected as criteria in the ahp method# also, peroxidase from mustard, peroxidase from horseradish, peroxidase from lignin and oxidase from polyphenol were proposed for this study# expert choice software has been applied to evaluate the ahp process# the analyze of various criteria indicated that the cost parameter with 31#3% preference was chosen as the main criteria, as well as the oxidase from polyphenol was selected as the proposed alternative with 28#1% of priority#
