Bisphenol A degradation and mineralization by the Fenton and the Photo-Fenton process

Abstract

The performance of the Fenton and photo-Fenton processes for the degradation and mineralization of Bisphenol A was investigat-ed. A parameterized kinetic model was suitably fitted to the exper-imental data in order to determine two performance parameters related to the global equilibrium conversion and kinetic rate of the process. Further analysis allowed selecting those process condi-tions (iron and hydrogen peroxide load) that maximize the process performance. The Fenton process clearly proved to more efficient-ly degrade Bisphenol A under irradiation. The highest conversion rates were achieved with only the stoichiometric hydrogen perox-ide load and the appropriate iron load (i.e. total Bisphenol A elimination and 90 % TOC decay).
