“…Over the past decade, ZVI was demonstrated for treating different varieties of organic and inorganic contaminants such as dyes ( Wang et al, 2017 ), phenolic compounds ( Ambika et al, 2020 , Minella et al, 2019 ), antibiotics ( Zhou et al, 2019 ), nitroaromatic compounds (NACs) ( Zarei et al, 2019 ), arsenic ( Tucek et al, 2017 ), heavy metals ( Li et al, 2017 ), chlorinated organic compounds ( Ezzatahmadi et al, 2017 ), nitrates etc ( Ezzatahmadi et al, 2017 ) . The heavy metal iron content in wastewater poses significant challenges during its treatment ( Demirbas, 2008 , Fu and Wang, 2011 ).…”

Heterogeneous Fenton catalysts are emerging as excellent systems for applications related to water purification. In this review, recent trends in the synthesis and application of heterogeneous Fenton catalysts for the abatement of organic pollutants and disinfection of microorganisms are discussed. It is noted that as the complexity of cell wall increases, the resistance level towards various disinfectants increases and it requires either harsh conditions or longer exposure time for the complete disinfection. In case of viruses, enveloped viruses ( e.g. SARS-CoV-2) are found to be more susceptible to disinfectants than the non-enveloped viruses. The introduction of plasmonic systems with the Fenton catalysts broaden the visible light absorption efficiency of the hybrid material, and incorporation of semiconductor material improves the rate of regeneration of Fe(II) from Fe(III). A special emphasis is given to the use of Fenton catalysts for antibacterial applications. Composite materials of magnetite and ferrites remain a champion in this area because of their easy separation and reuse, owing to their magnetic properties. Iron minerals supported on clay materials, perovskites, carbon materials, zeolites and metal-organic frameworks (MOFs) dramatically increase the catalytic degradation rate of contaminants by providing high surface area, good mechanical stability, and improved electron transfer. Moreover, insights to the zero-valent iron and its capacity to remove a wide range of organic pollutants, heavy metals and bacterial contamination are also discussed. Real world applications and the role of natural organic matter are summarised. Parameter optimisation (e.g. light source, dosage of catalyst, concentration of H 2 O 2 etc. ), sustainable models for the reusability or recyclability of the catalyst and the theoretical understanding and mechanistic aspects of the photo-Fenton process are also explained. Additionally, this review summarises the opportunities and future directions of research in the heterogeneous Fenton catalysis.

“…In recent years, the application of nanoscale zero-valent iron (nZVI) in the in situ remediation of Cr(VI)-contaminated soil has attracted extensive attention [24]. nZVI is a kind of material, which is generally in powder form, and its particle size generally lies within the range of 10-100 nm [25]. The original nZVI was prepared by reducing iron [26] with NaBH 4 , and in the laboratory [27], the original nZVI was synthesized by reducing FeCl 3 with NaBH 4 .…”

Chromium (Cr) is a common toxic heavy metal that is widely used in all kinds of industries, causing a series of environmental problems. Nanoscale zero- valent iron (nZVI) is considered to be an ideal remediation material for contaminated soil, especially for heavy metal pollutants. As a material of low toxicity and good activity, nZVI has been widely applied in the in situ remediation of soil hexavalent chromium (Cr(vi)) with mobility and toxicity in recent years. In this paper, some current technologies for the preparation of nZVI are summarized and the remediation mechanism of Cr(vi)-contaminated soil is proposed. Five classified modified nZVI materials are introduced and their remediation processes in Cr(vi)-contaminated soil are summarized. Key factors affecting the remediation of Cr(vi)-contaminated soil by nZVI are studied. Interaction mechanisms between nZVI-based materials and Cr(vi) are explored. This study provides a comprehensive review of the nZVI materials for the remediation of Cr(vi)-contaminated soil, which is conducive to reducing soil pollution.

“…It has been reported that nZVI particles are proven to be the most promising and efficient substances in the removal of various antibiotics from wastewater. The nZVI particles being strong, highly reactive, and possessing abundant reactive sites, are capable of eliminating various antibiotics from wastewater (Zhou et al, 2019). However, nZVI has few limitations (Dong et al, 2018a) like the passivation of active sites and diminished reactivity/efficiency due to the development of oxide layer on the nZVI surface.…”

In this study, FeNi nanoparticles were green synthesized using Punica granatum (pomegranate) peel extract, and these nanoparticles were also formed in situ over quartz sand (GS-FeNi) for removal of tetracycline (TC). Under the optimized operating conditions, (GS-FeNi concentration: 1.5% w/v; concentration of TC: 20 mg/L; interaction period: 180 min), 99AE0.2% TC removal was achieved in the batch reactor. The removal capacity was 181AE1 mg/g. A detailed characterization of the sorbent and the solution before and after the interaction revealed that the removal mechanism(s) involved both the sorption and degradation of TC. The reusability of reactant was assessed for four cycles of operation, and 77AE4% of TC removal was obtained in the cycle. To judge the environmental sustainability of the process, residual toxicity assay of the interacted TC solution was performed with indicator bacteria (Bacillus and Pseudomonas) and algae (Chlorella sp.), which confirmed a substantial decrease in the toxicity. The continuous column studies were undertaken in the packed bed reactors using GS-FeNi. Employing the optimized conditions, quite high removal efficiency (978AE5 mg/g) was obtained in the columns. The application of GS-FeNi for antibiotic removal was further evaluated in lake water, tap water, and ground water spiked with TC, and the removal capacity achieved was found to be 781AE5, 712AE5, and 687AE3 mg/g, respectively. This work can pave the way for treatment of antibiotics and other pollutants in the reactors using novel green composites prepared from fruit wastes.
