“…Firstly, when MC came into contact with the laccase molecule, it first bound to the T1-Cu atomic site in the center of laccase and induced an electron, which would then transferred through the Cys-His pathway and reduced other copper ions, and finally reduced oxygen molecules to water in the nuclear center. 55 In this process, due to the attack of active species, functional groups such as the amino group, carboxyl group and n -methyl group in MC would undergo cleavage and ring-opening reactions and turn into some small molecule organics, which would be further dehydrogenated and oxidized, and eventually form CO 2 and H 2 O. 56 Its degradation equation could be simplified as follows:4H + + 4e − + O 2 → 2H 2 O…”

“…Different synthesis approaches of Fe-based nanomaterials production include co-precipitation, proprietary copyrolysis, solvothermal, sol-gel, emulsion polymerization, hydrothermal, sonochemical, thermal decomposition and green synthesis methods (Yadav et al, 2020a;Otero-González et al, 2020;Singh et al, 2020;Torasso et al, 2021;Selvaraj et al, 2022). Green synthesis methods of Fe-based nanomaterials are environmentally benign and could be considered as a potential substitute of existing chemical and physical methods due to the affordability, abundance of biomaterials and simple operating procedures (Arslan et al, 2022;Xu et al, 2022).…”

“…Major pollutants are organic compounds, dyes, heavy metals (Pb, As, Hg, Cu, Fe, Ni, Pd, etc. ), agricultural and industrial wastes, recalcitrant compounds, and spills (Lin et al, 2022;Moreira et al, 2021;Zamora-Ledezma et al, 2021;Moosavi et al, 2020;Qi et al, 2023;Bhardwaj et al, 2022.). It was noted that prolonged consumption of arsenic-containing water could lead to severe health conditions in humans, including arsenicosis, cardiovascular disease, diabetes, and cancer.…”

Arsenic decontamination is a major worldwide concern as prolonged exposure to arsenic (>10 µg L-1) through drinking water causes serious health hazards in human beings. The selection of significant, cost-effective, and affordable processes for arsenic removal is the need of the hour. For the last decades, iron-oxide nanomaterials (either in the magnetite or bimetallic form) based adsorptive process gained attention owing to their high arsenic removal efficiency and high regenerative capacity as well as low yield of harmful by-products. In the current state-of-the-art, a comprehensive literature review was conducted focused on the applicability of iron-based nanomaterials for arsenic removal by considering three main factors: (a) compilation of arsenic removal efficiency, (b) identifying factors that are majorly affecting the process of arsenic adsorption and needs further investigation, and (c) regeneration capacity of adsorbents without affecting the removal process. The results revealed that magnetite and bimetallic nanomaterials are more effective for removing Arsenic (III) and Arsenic (V). Further, magnetite-based nanomaterials could be used up to five to six reuse cycles, whereas this value varied from three to six reuse cycles for bimetallic ones. However, most of the literature was based on laboratory findings using decided protocols and sophisticated instruments. It cannot be replicated under natural aquatic settings in the occurrence of organic contents, fluctuating pH and temperature, and interfering compounds. The primary rationale behind this study is to provide a comparative picture of arsenic removal through different iron-oxide nanomaterials (last twelve yearsof published literature) and insights into future research directions.

“…Laccase has the ability to degrade a wide range of substrates, including both phenolic and non-phenolic compounds. It possesses outstanding catalytic activity and non-specific oxidation ability, making it more effective than other enzymes (Bhardwaj et al 2022) After 15 cycles of reuse, the immobilized enzyme retained 90% of its BPA degradation ability (Brugnari et al 2018). Based on the reviewed literature, there is potential to use advanced environmentally friendly and cost-effective support materials to immobilize laccase.…”

Bisphenol A (BPA), an endocrine disruptor widely used in industrial production, is found in various environmental sources. Despite numerous reports on BPA degradation and removal, the details remain unclear. This paper aims to address this gap by providing a comprehensive review of BPA degradation methods, focusing on biological, physical, and chemical treatments, and the factors that affect the degradation of BPA. Firstly, the paper uses VOSviewer software to map out the literature on BPA degradation published in the past 20 years, which reveals the trends and research focus in this field. Next, the advantages and limitations of different BPA degradation methods are discussed. Overall, this review highlights the importance of BPA degradation to protect the environment and human health. The paper provides significant insights for researchers and policymakers to develop better approaches for BPA degradation and removal.
