Degradation kinetics and mechanism of hazardous metribuzin herbicide using advanced oxidation processes (HC & HC+ H2O2)

Peroxydisulfate-assisted sonocatalytic degradation of metribuzin by La-doped ZnFe layered double hydroxide

“…According to the structure of metribuzin, the degradation should first start with desulfurization and deamination [5] , [56] . The degradation of metribuzin occurs mainly as a result of the breaking of the C—C, C—N, C—S, and N—N bonds [57] . The reactive species, SO 4 −• and O 2 •− , that are produced during the process are responsible for the degradation.…”

“…Additionally, it may cause liver damage in mice at high dosages of 200 mg kg −1 [3] . Various water treatment processes, including adsorption [4] , chemical oxidation [5] , and advanced oxidation processes (AOPs) [6] have been developed to treat water containing metribuzin. AOPs are effective and environmentally-friendly methods for converting target pollutants into carbon dioxide (CO 2 ) and water (H 2 O) by generating reactive oxygen species (ROS) [7] .…”

A Review on Rotary Generators of Hydrodynamic Cavitation for Wastewater Treatment and Enhancement of Anaerobic Digestion Process

“…However, in the last decade HC has been widely recognized as a possible wastewater treatment method due to its effective destruction of exclusively associated with engineering problems, such as noise, vibration and cavitation erosion (indicators of reduced machine efficiency). However, in the last decade HC has been widely recognized as a possible wastewater treatment method due to its effective destruction of complex organic chemicals, nonchemical nature, good compatibility with other advanced oxidation processes, ease of operation, excellent generation of the required intensities of cavitation conditions, possible pilot scale application, good experimental results and economic aspects [6][7][8][9][10][11]. An increasing number of published documents on the keywords "hydrodynamic cavitation" and "wastewater treatment," and "cavitation and wastewater treatment" can be seen in Figure 1.…”

Degradation of metribuzin in the UV/chlorine process: kinetic model, degradation by-products and transformation pathways

“…9,10 Given that metribuzin has half-lives between 5 and 50 days, this pollutant in the aquatic environment is regarded as presenting possible hazards not only to the environment but also to human health. 11,12 The maximum permissible concentration of metribuzin in drinking water is 0.08 milligrams per liter. 5 However, conventional drinking water treatment techniques are unable to effectively remove herbicides residues.…”
