The experimental investigation of bisphenol A degradation by Fenton process with different types of cyclodextrins

摘要

In this work, the degradation efficiencies of bisphenol A (BPA) by Fenton reaction were compared systematically with varying cyclodextrins. The results showed that the removal rate of BPA displays a considerable increase by Fenton reaction in presence of beta-cyclodextrin (beta-CD) and its derivatives. Specifically, 98 +/- 2% and 89 +/- 2% of BPA was removed with carboxymethyl-beta-cyclodextrin (CMCD) and beta-CD, respectively. Additionally, to understand the reaction mechanism, the structure activity of cyclodextrins with substrate and the kinetic of Fenton reaction with cyclodextrins have been investigated. Results showed that the structure activity was the major role for cyclodextrins in this system. (C) 2017 The Korean Society of Industrial and Engineering Chemistry. Published by Elsevier B.V.
