Exploring the pressurized heterogeneous electro-Fenton process and modelling the system

The ability of recycled magnetite nanoparticles to degrade carbamazepine in water through photo-Fenton oxidation at neutral pH

“…Thus, the addition of 1 mM of hydrogen peroxide degrades CBZ by more than 50% after 2 hours of irradiation. However, it is evident that there is a limit HP concentration in the studied conditions, beyond which the reaction between hydrogen peroxide and • OH will be too important and lead to slower degradation of CBZ [35]. We observed that increasing the concentration of HP from 2 mM to 3 mM resulted in only a 19% difference in degradation efficiency, however, 2 mM was chosen as the optimal concentration to avoid the need for additional chemicals in the process.…”

Peroxymonosulfate Activation by Different Synthesized CuFe-MOFs: Application for Dye, Drugs, and Pathogen Removal

“…It was highlighted by the formation of several compounds such as oxalic, succinic, formic, malonic, and acetic acid. The obtained results of short-chain carboxylic acids and the generation of intermediates that correspond to peaks detected by measurement on high-performance liquid chromatography (HPLC), not identified or quantified, are indicative of the generation of reaction products [63]. In Figure 8, the intermediates detected with the systems UV/[CuFe(BDC-NH 2 ) R , CuFe(BDC-NH 2 ) S , CuFe(BDC-NH 2 ) D ]/PMS are presented as HPLC area.…”

Exploring the use of carbon materials as cathodes in electrochemical advanced oxidation processes for the degradation of antibiotics

“…The iron was incorporated to the low-cost carbon materials upon immobilization on either the powders of the carbon materials before the fabrication of the cathodes (this procedure will be referred to as "pre"), or directly on the cathodes (this procedure will be referred to as "post"). The carbon felt was not further used for the immobilization of iron, since our previous works have shown that carbon felts are not the best candidates for a potential scaling up of the process [27,28].…”

“…Among them, carbon felts are most widely used carbon cathodes in EAOP; however, despite the good performance obtained for the degradation of different pollutants, the cost of this material prevents its large scale utilization [25,26]. Indeed, our previous studies on the scalingup of EF treatments have pointed out that carbon felt cathodes are not adequate in scaled-up flow systems due to its flexibility, while cathodes prepared upon casting of a powder material and a binder on a titanium mesh support are more robust [27,28]. Some other supports have also been reported in the literature [29,30].…”
