Abstract

Hydrogen peroxide, an oxidizing agent used in organic syntheses, discoloration processes and bleaching and in the treatment of effluents, can be generated by the reduction of oxygen in watery solutions. In this project, the objective is to develop and make commercial and process an item of equipment for the electrosynthesis of hydrogen peroxide for use in the oxidization of organic compounds and in the treatment of industrial effluents. In phase 1 of the project a study was carried out into the viability of the proposal by means of benchtop trials. Phase 2 will involve the assembly of a prototype of electrochemical reactor. The intention is to structure the design, the manufacture, assembly, installation and begin to operate the equipment for the production of hydrogen peroxide. Subsequently, studies will be carried out to optimize the functionality with regard to the speed of electrogeneration and the electric efficiency. Intensive operation will also serve to establish operating routines, the useful life of the components, the periodicity of preventative maintenance and the operation and maintenance costs. The intensive operation tests will include the electrogeneration of the oxidizing compound in the in situ treatment of simulated watery effluents. For these tests effluents containing the reactive colorant Remazol Black and also the acidic herbicide, 2,4-Dichlorophenoxyacetic acid (2,4-D) will be used. (AU)
