Degradation of acephate using combined ultrasonic and ozonation method

Degradation of Acephate and Its Intermediate Methamidophos: Mechanisms and Biochemical Pathways

“…The advantages of physical adsorption and chemical degradation methods lie in their broad spectrum of pollutants, their adaptability to the environment, and their effectiveness. Advanced oxidation processes (AOPs) are a more efficient composite technology that combines the advantages of different physicochemical degradation methods to more efficiently remove methamidophos and acephate; examples of these methods include photo-Fenton process, UV/TiO 2 , and ultrasonic ozonation (Dai et al, 2008;Wang et al, 2015;Zheng et al, 2016).…”

“…Ultrasound and ozonization have synergistic effects in complex systems. The degradation efficiency of acephate ozonization can be increased from 60.6 to 87.6% in 60 min with 160 kHz ultrasound irradiation because it can improve the oxidizability of nitrogen atoms (Wang et al, 2015 (Fu et al, 2012). TiO 2 is often used as a catalyst due to its advantages of low cost, good chemical stability, and high catalytic activity.…”

“…photo-Fenton processes, UV/TiO 2 , ultrasonic ozonation, and ionizing irradiation, etc. are widely studied for acephate or methamidophos (Dai et al, 2008;Wang et al, 2015;Yang et al, 2015;Zheng et al, 2016). Efficient and environmentally friendly microbial degradation has been considered as the most promising remediation method (Cycoń and Piotrowska-Seget, 2016;Bhatt et al, 2019;Pang et al, 2020;Feng et al, 2020;Zhang et al, 2020).…”

Sonochemical degradation of pesticides in aqueous solution: investigation on the influence of operating parameters and degradation pathway – a systematic review

“…The formation of the large bubbles decreases the bubble-liquid interfacial region considerably, with a consequent reduction in the O 3 transfer rate from the gas phase to the liquid phase. 70,91 Wang et al 72 reported that the degradation efficiency of acephate by combined ultrasonic/ozonation method was 27% greater than the degradation efficiency when individual ozonation method was used aer 60 min.…”

A Review on Ultrasonic Catalytic Microbubbles Ozonation Processes: Properties, Hydroxyl Radicals Generation Pathway and Potential in Application

“…In most studies, additional OH· plays a major role in pollutants removal; however, according to WanQian Guo et al [88], direct oxidation via ozone molecular was responsible for sulfamethoxazole degradation. The degradation efficiency of acephate and degradation products have also been studied [89].…”
