ABSTRACT: Powerful ultrasound is an attractive technology used in environmental remediation to degrade recalcitrant anthropogenic contaminants. However, natural organic matters (NOMs), ubiquitously present in surface and ground waters participate and affect the ultrasonic degradation process. The changes to NOM properties suggest that ultrasound may significantly affect NOM-pollutant interactions (e.g., facilitate desorption of hydrophobic organics from NOMs or promote complexation between metallic cations and NOMs). In addition, several examples are presented for ultrasonic degradation of emerging anthropogenic contaminants.
