Kinetic degradation of amoxicillin by using the electro-Fenton process in the presence of a graphite rods from used batteries

Abstract

This study reports the removal of amoxicillin (AMX) in aqueous media using the electro-Fenton process in the presence of a graphite cathode recovered from used batteries. The impact of the relevant parameters on the electro-Fenton process, namely the applied current intensity, the temperature, the initial concentration of AMX and the initial concentration of ferrous ions were investigated. The results showed that the optimal values were: I= 600 mA, T= 25°C, [AMX] 0 = 0.082 mmol•L −1 and [Fe 2+ ]= 1 mmol•L −1 , leading to 95% degradation and 74% mineralization. The model parameters of AMX mineralization were determined using nonlinear methods, showing that it follows a pseudo-second-order kinetic. The Energy consumption (EC) calculated under the optimal values was found to be 0.79 kW•h −1 •g −1 , which was of the same order of magnitude of those reported in other findings; while it is noteworthy that the electrodes used in our study are of a lower cost.

Study of The Performance of A Cylindrical Flow-Through Electro-Fenton Reactor Using Different Arrangements of Carbon Felt Electrodes: Degradation of Amoxicillin In Aqueous Solution

“…It is interesting to compare the AMX mineralization data obtained in this study with reports using electro-Fenton process. In this way, Kadji et al (2021) obtained 74% of AMX mineralization after 180 min of electrolysis, with an initial AMX concentration of 0.082 mM; however, this value was reduced to 39% at 0.164 mM of AMX due to a competitive consumption of oxidizing  OH radicals between AMX and the by-products formed during experiments (Kadji et al 2021). On the other hand, Garza-Campos et al…”

Heterogeneous degradation of amoxicillin in the presence of synthesized alginate-Fe beads catalyst by the electro-Fenton process using a graphite cathode recovered from used batteries

“…The concentrations of these compounds have been reported to be in the range of mg=L (Elizalde-Velázquez et al 2016). Even at low concentrations, the presence of antibiotics in surface and groundwater constitutes a great threat for the ecosystem (Kadji et al 2021). Thus, exposure to antibiotics cannot only lead to growth stunting and body weight reduction in aquatic organisms, but also to the development of antibiotic resistance genes in pathogenic bacteria which constitutes a dangerous threat to human health, since the effectiveness of the treatment of bacterial infections is reduced (Kumar et al 2021).…”

“…The adsorption is one of the most effective and low cost methods, however, this technique have some disadvantages such as non-destructive and merely transfer pollutants from one phase to another, what always result in a secondary pollution (Madi-Azegagh et al 2018a, 2018b. The biological methods such as activated sludge process and anaerobic treatment, the most cost-effective for wastewater treatment, which are destructive and have been extensively studied, do not always appear relevant for the removal of, owing to their low biodegradability (Ikhlef-Taguelmimt et al 2020;Kadji et al 2021). However, these techniques are not adapted for the treatment of antibiotics residues owing to their recalcitrance (Annabi et al 2016;Dogan & Kidak 2016).…”

A comparative study of ceramic nanoparticles synthesized for antibiotic removal: catalysis characterization and photocatalytic performance modeling

“…in addition, antibiotics are the main concern of researchers all over the world if compared to the other categories of pharmaceutical products because of their increasing aquatic toxicity and nonbiodegradabilty in the environment (Mostafaloo et al 2019;Aissani et al 2020). Generally, antibiotics are present at amounts ranging from ng/L to μg/L in treated wastewater (Ikhlef-Taguelmimt et al 2020;Kadji et al A c c e p t e d m a n u s c r i p t 2020). Even at very low amounts, the existence of these substances in water resources, enhances bacterial resistance (Shooshtari and Ghazi 2017).…”

“…Conventional methods cannot effectively eliminate antibiotic residues due to antibacterial nature (Chen and Huang 2010;Li and Zhang 2010;Gao et al 2012). In this respect, Advanced Oxidation Processes (AOPs) have proven to be a suitable alternative for the rapid destruction of recalcitrant and non-biodegradable compounds in contaminated waters (Lou et al 2017;Aboudalle et al 2018;Kamagate et al 2018;Yahiaoui et al 2018;Kadji et al 2020). The heterogeneous photocatalysis process in particular has been successfully used to degrade different types of pharmaceutical drugs and organic compounds (Zhu et al 2013;Aissani et al 2018Aissani et al , 2020Hou et al 2019;Ikhlef-Taguelmimt et al 2020;Shan et al 2020).…”
