Removal of PAHs from Road Drainage System by Ultrasonication
2021
The articles reveal the removal effectiveness of 7 polycyclic aromatic hydrocarbons (PAHs), which were recognized in water from a highway drainage system by using the ultrasound treatment process. Results showed that after 45 min of sonication, the average removal of PAHs reached 59%. The reduction of analyzed substances was proportional to treated time and irradiation amplitude. Furthermore, as a consequence of ozone addition to the sonicated samples, the efficiency of the treatment was significantly higher.
