Abstract

In this work, we present a comparative analysis of the degradation of aqueous solutions of PCE by sonochemical, electrochemical and sonoelectrochemical treatment, pointing out the advantages and drawbacks of the different approaches, and also the synergic effects of the simultaneous applications of both energetic fields: ultrasound and electricity. Prior to these studies, not only were specific researches carried out in order to develop stable components (anodic materials) under high power ultrasound fields, but the experimental devices used during this study were also characterized. In summary, the sonochemical method presents serious deficiencies not only from an environmental point of view but also in its energetic requirements. The electrochemical method presents competitive costs and feasible technically processes (using optimized filter-press reactors), but it does not suit the environmental requirements. The sonoelectrochemical treatment has provided the best results from technical and environmental points of view but economical issues must be improved. Further research lines are suggested on the basis of the obtained results.
