TI  - Modified Fenton reaction for trichlorophenol dechlorination by enzymatically 
      generated H2O2 and gluconic acid chelate.
PG  - 2193-200
AB  - Glucose oxidase is a well-known enzyme that catalyzes the oxidation of 
      beta-D-glucose to produce gluconic acid and hydrogen peroxide. Fenton reaction is 
      a powerful oxidation technology used for the oxidation of groundwater pollutants. 
      For the application of Fenton reaction in groundwater remediation, successful 
      operation of Fenton reaction near neutral pH, and on-site generation of both H2O2 
      and chelate will be beneficial. The focus of this experimental study was to 
      couple the glucose oxidation reaction with chelate-based Fenton reaction. The 
      idea was to use the hydrogen peroxide and chelate gluconic acid generated during 
      glucose oxidation for the dechlorination of 2,4,6-trichlorophenol (TCP) by Fenton 
      reaction. The oxidation of glucose was achieved using the enzyme in free and 
      immobilized forms. The rate of production of hydrogen peroxide was determined for 
      each system, and was used to estimate the time required for complete consumption 
      of glucose during the process, thus avoiding any traces of glucose in the Fenton 
      reaction. In the case of free enzyme reaction, separation of the enzyme was 
      achieved using an ultrafiltration membrane before initiating the Fenton reaction. 
      The oxidation of TCP by Fenton reaction was performed at varying ratios of 
      gluconic acid/Fe, and its effect on the decomposition of TCP and H2O2 was 
      studied. TCP degradation was studied both in terms of parent compound degradation 
      and free chloride generation.
