Paper Title:
Catalytic Oxidation of 4,4'-Dibromobiphenyl in Sub-Critical Water with Mn0.9-Co0.1-Ce-Oxide
  Abstract

A complex mental oxide Mn0.9-Co0.1-Ce-oxide was prepared by co-precipitation-hydrothermal method and it was used as catalyst to oxidative degradation of 4,4- dibromobiphenyl (4,4’-DBB) in subcritical water. The optimization conditions is obtained as follows: 5% Mn0.9-Co0.1-Ce-oxide catalyst, m(H2O2):m(4,4’-DBB)=200:1,temperature of 613K, reaction time of 20 minutes, and COD removal rate is more than 99 %. In the temperature range of 603–633 K, the degradation kinetics is studied and apparent activation energy is 35.92 and 46.69 kJ/mol for no catalyst and 5% Mn0.9-Co0.1-Ce-oxide, respectively.
