Hybrid Sonochemical Treatments of Wastewater: Sonophotochemical and Sonoelectrochemical Approaches. Part II: Sonophotocatalytic and Sonoelectrochemical Degradation of Organic Pollutants

Abstract

Sonochemical oxidation is one of the advanced oxidation techniques that are widely used to decompose various organic contaminants in aqueous environment. Recent studies have suggested that the use of hybrid techniques is more effective compared to individual techniques for the decomposition of organic contaminants. The combination of more than one oxidation technique overcomes the disadvantages of individual techniques. This chapter provides a very detailed analysis of the sonochemical, sonophotocatalytic, and sonoelectrochemical degradation of various organic pollutants in aqueous environment. In addition to providing experimental data including kinetic information on the degradation reactions, specific examples have been analyzed in terms of their reaction mechanisms.
