Electrochemical degradation of chloramphenicol with a novel Al doped PbO2 electrode: Performance, kinetics and degradation mechanism

Degradation of Chloramphenicol in Synthetic and Aquaculture Wastewater Using Electrooxidation

“…Even though a difference of 1.3% was recorded between the prediction and the actual result, the model can be considered as precise and valid. Although here we studied CAP removal with electrooxidation, in the study by Chen et al, (2015), 87.3% of CAP removal and 52.1% of mineralization (500 mg L −1 initial CAP concentration) was reached after 2.5 h electrolysis with 0.2 mol dm −3 of Na 2 SO 4 at a current density of 30 mA cm −2 and an Al/PbO 2 electrode. The corresponding half‐life was 49.8 min under these conditions.…”

“…Treatment time and current intensity had the greatest effect on CAP removal, at 54.6 and 34.4%, respectively. The large effect of current intensity is a reflection of this parameter's control of the amount of OH − radicals and other oxidants produced in the reactor (Zaviska et al, 2013; García‐Gómez et al, 2014; Chen et al, 2015). However, the impact of the pollutant's initial concentration ( X 2 ) on the investigated response was relatively low (6.75%).…”

“…Any presence of residual CAP in aquatic‐animal tissue points to the use of this product in a farming pond. Chen et al (2015) found concentrations of CAP up to 28.4 ng L −1 in urban water supplies in Shanghai, China, and Molina‐Avila (2015) found 0.103 mg L −1 in aquaculture waste‐water effluent in the south of the Sonora, Mexico. Mitchell et al (2015) found that hydrolysis of CAP under ambient conditions did not deteriorate its structure.…”

Electrocatalytic degradation of aniline by Ti/Sb–SnO2, Ti/Sb–SnO2/Pb3O4 and Ti/Sb–SnO2/PbO2 anodes in different electrolytes

“…Some researchers [24,[40][41][42] assumed that Ti/SnO 2 and Ti/PbO 2 were considered as non-active electrodes comparing to Ti/RuO 2 or Ti/ IrO 2 . However, according to our previous comparisons, the Ti/PbO 2 electrode was more active compared with Ti/SnO 2 electrode in this experiment [43].…”

Preparation and electrochemical property of TiO2/Nano-graphite composite anode for electro-catalytic degradation of ceftriaxone sodium

“…There are some kinds of AOPs have been researched, such as photo-catalysis [5], photoelectro-catalysis [6,7] and electrocatalysis [8], of which electro-catalysis has the characteristics of low requirement to the equipments and reaction condition, simple operation, and the generation of some high active species like hydrogen peroxide (H 2 O 2 ) [9,10] and hydroxyl radical ( OH) [11] produced on the surface of the electrodes to degrade organic contaminants effectively. However, most advanced electrochemical oxidation process (AEOP), one of new AOPs, treated high concentration organic wastewater [12][13][14][15], their high current and high voltage will consume more energy sources, what's more, in the condition of high current density, many by-products will be generated when degrading the organic wastewater [16][17][18]. Thus, it's a promising choice to catalyze and oxidate the low concentration organics with low voltage.…”
