Electrochemical degradation of chlorpyrifos pesticide in aqueous solutions by anodic oxidation at boron-doped diamond electrodes

Study of degradation intermediates formed during electrochemical oxidation of pesticide residue 2,6-dichlorobenzamide (BAM) at boron doped diamond (BDD) and platinum–iridium anodes

“…Classification of common electrode materials have been performed by the group of Comninellis (Comninellis et al, 2008;Kapałka et al, 2009), who presents boron doped diamond (BDD) as the limit of the non-active anodes and DSA anodes as the limit of the active anodes. Non-active anodes generally present the highest efficiencies considering the EOTR and have usually been found to be superior concerning rate of reaction and mineralization efficiency (Sirés et al, 2008;Samet et al, 2010;Malpass et al, 2013).…”

Application of BDD thin film electrode for electrochemical decomposition of heterogeneous aromatic compounds

“…Organic pollutants on BDD electrodes can be oxidized directly (by electron transfer from surface to compound) and indirectly (by oxidizing entities generated on the electrode surface by electrolysis of water) [2]. It has also been demonstrated that other biorefractory compounds such as pesticides, pharmaceuticals and dyes can be completely mineralized with high current efficiency [13][14][15]. Electrochemical study was performed to achieve and optimize the parameters of this process.…”

Reduction in energy consumption of electrochemical pesticide degradation through combination with membrane filtration

“…This strategy provides some degree of control over DIs and byproducts, since these are separated from the treated membrane permeate, and also the AOP only needs to be applied to around 10-30% of the water in the retentate stream. Furthermore, due to the reduction in volume, the micropollutant concentration will increase, and this has been found to lead to more energy efficient degradations due to the fact that AOP mediated degradation follows pseudo first order kinetics in most typical modes of operation [7][8][9][10] as described with Eq. (1):…”
