Kinetics and mechanism of low-frequency ultrasound driven elimination of trace level aqueous perfluorooctanesulfonic acid and perfluorooctanoic acid
Perfluorooctanesulfonic acid (PFOS) and Perfluorooctanoic acid (PFOA) are the most
investigated persistent organic pollutants due to their adverse health concerns and inertness
in elimination. The wastewater treatment of PFOX (PFOS and PFOA) has been investigated
by sonochemical method while implementing a 20-kHz probe-type sonicator with ultrasound
power variance from 150 to 375 W. Highest degradation rate was achieved under optimum
parameters such as PFOX initial concentration, ultrasound power level, solution pH and …
