Parameter optimization and degradation mechanism for electrocatalytic degradation of 2,4-diclorophenoxyacetic acid (2,4-D) herbicide by lead dioxide electrodes

Abstract

Optimization of process parameters by the CCD method and electrocatalytic degradation and the electrochemical degradation mechanism of 2,4-D using modified electrode anodes were investigated.

Selected pharmaceuticals removal using algae derived porous carbon: experimental, modeling and DFT theoretical insights

“…To obtain optimum operational parameters that affect ketoprofen and aspirin adsorption onto PCLD@NaOH, response surface methodology (RSM) was used to this purpose. 26,[93][94][95][96] In Table 8, we present the experimental levels of ketoprofen and aspirin adsorption on PCLD@NaOH, respectively. In addition, the experimental results were obtained by using the CCD matrix (Table 1S †).…”

Moving-bed biofilm reactor combined with three-dimensional electrochemical pretreatment (MBBR–3DE) for 2,4-D herbicide treatment: application for real wastewater, improvement of biodegradability

“…These compounds are used to control broadleaf weeds in corn, small grains, sorghum, rice and sugarcane elds, and pasture and rangeland and grass plants. 1,2 Phenoxy herbicides are highly soluble in water; therefore, they are easily leached and found in surface and groundwater sources; 3 so that in many areas, they can be determined even in drinking water. 4 These herbicides have low biodegradability and toxicity (carcinogenic, teratogenic, mutagenic, adverse effects on the endocrine system, hepatotoxicity, and renal toxicity).…”

Degradation of azo dye Acid Red 14 (AR14) from aqueous solution using H2O2/nZVI and S2O82–/nZVI processes in the presence of UV irradiation

“…Contamination of water resources occurs via different pollutants such as dyes, toxic metal ions, and oil, which are released to the environment from different industries (e.g., textile, food, cosmetics, plastics, paper, and printing) (Akerdi, Bahrami, Arami, & Pajootan, 2016; Dargahi et al, 2019; Shokoohi, Jafari, Dargahi, & Torkshavand, 2017; Thiam, Sirés, Centellas, Cabot, & Brillas, 2015). Among these industries, it has been recognized that water is highly consumed through different processes applied in textile industries (dyeing, finishing, scouring, etc.)…”
