Enhanced peroxymonosulfate activation for sulfamethazine degradation by ultrasound irradiation: Performances and mechanisms

In this study, ultrasound (US) technology was adopted for peroxymonosulfate (PMS) activation, and it increased the efficiency of sulfamethazine (SMT) antibiotic degradation. US can considerably activate PMS, increasing the SMT degradation rate by the US/PMS process up to 6.4 and 86 times that of PMS alone and US alone processes, respectively. The scavenger quenching experiments and electron paramagnetic resonance (EPR) spectrometry proved that...
