A novel bio-electro-Fenton system with dual application for the catalytic degradation of tetracycline antibiotic in wastewater and bioelectricity generation

Abstract

In this new insight, the potential application of the Bio-Electro-Fenton system was surveyed with the aim of simultaneous degradation of tetracycline and in situ generation of renewable bioenergy without the need for an external electricity source.

A review on bio-electro-Fenton systems as environmentally friendly methods for degradation of environmental organic pollutants in wastewater

“…43,79,80 Among electrogenic bacteria, Geobacter and Shewanella are well-known species with capable of extracellular electron transfer (EET) that attach to the electrode and form a biofilm layer. 81 A list of some typical electrogenic microorganisms is shown in Fig. 5.…”

“…Later, ˙OH reacts with resistant organic pollutants, leading to their decomposition ( eqn (6) ). 81 There are different types of homogeneous or heterogeneous iron sources that are used as Fenton catalysts in BEFs. Fig.…”

Application of MIL-53(Al)-NH2 as a Dispersive Microsolid-Phase Extraction Material for Determination of Cyclophosphamide in Urine by High-Performance Liquid Chromatography

“…So, the important effective parameters such as selectivity, surface area, chemical stability, and nonreactivity of the solid sorbent should be considered . To date, various solid sorbents have been used in the Dμ-SPE method to extract different analytes from the liquid matrices. − In this regard, the metal–organic framework (MOF) materials have been exploited on the Dμ-SPE method for extraction of chlorinated insecticides, herbicides, hormones, polyaromatic hydrocarbons, parabens, and sulfonamides. − MOFs are versatile porous materials consisting of metal clusters or ions and organic ligands, which have a repeatable crystal structure and controllable chemical structure. , These materials with eye-catching features such as high surface area, porosity, tunable and uniform pores, tunable morphologies, and fully assessable active sites have been used in various research studies. − Previous research of this group has focused on the sampling, extraction, and determination of different environmental pollutants from air and urine conditions by utilizing various MOFs. − In this work, MIL-53­(Al)-NH 2 as a well-known and reliable solid sorbent with high surface area, high chemical stability, high thermal resistance, and high porosity was utilized in the extraction of the cyclophosphamide compound from the urine samples. − It is worth noting that the presence of an amine functional group in MIL-53­(Al)-NH 2 can be affected by the enhanced extraction efficiency through the hydrogen bonding of NH 2 with the NH group of the cyclophosphamide compound. , …”

Bioelectrochemical performance of microbial fuel cell powered electro-Fenton system (MFCⓅEFs) with composite PANI-Mn/CF anode

“…In recent years, microbial fuel cell powered electro-Fenton system (MFCⓅEFs) has garnered a growing amount of attention and developed as an ecologically friendly sustainable energy conversion technology capable of resource recovery and utilization [1][2][3]. The bio-electro-chemical reaction takes place in the anodic chamber of MFCⓅEFs, and electrochemically active bacteria oxidize organic substrates to generate bio-electrons and protons, which are transferred to the cathodic chamber via the external circuit and the proton exchange membrane, respectively [4][5][6], completing the conversion of biomass energy to electricity.…”
