“…Detailed procedures for the revival and propagation of MS2 can be found in Section S2. In summary, the standard double-layer agar method was used to enumerate MS2 using Tryptic Soy Agar (BD Difco 236950, Cat.DF0369176), with the MS2 concentration being ascertained via the plaque-forming unit (PFU) . Plates displaying between 20 and 300 plaques were chosen for counting.…”

The COVID-19 pandemic sparked public health concerns about the transmission of airborne viruses. Current methods mainly capture pathogens without inactivation, leading to potential secondary pollution. Herein, we evaluated the inactivation performance of a model viral species (MS2) in simulated bioaerosol by an electromagnetically enhanced air filtration system under a 300 kHz electromagnetic induction field. A nonwoven fabric filter was coated with a 2D catalyst, MXene (Ti 3 C 2 T x ), at a coating density of 4.56 mg•cm −2 to absorb electromagnetic irradiation and produce local heating and electromagnetic field for microbial inactivation. The results showed that the MXene-coated air filter significantly enhanced the viral removal efficiency by achieving a log removal of 3.4 ± 0.15 under an electromagnetic power density of 369 W•cm −2 . By contrast, the pristine filter without catalyst coating only garnered a log removal of 0.3 ± 0.04. Though the primary antimicrobial mechanism is the local heating as indicated by the elevated surface temperature of 72.2 ± 4 °C under the electromagnetic field, additional nonthermal effects (e.g., dielectrophoresis) on enhanced viral capture during electromagnetically enhanced filtration were investigated by COMSOL simulation to delineate the potential transmission trajectories of bioaerosol. The results provide unique insights into the mechanisms of pathogen control and thus promote alternative solutions for preventing the transmission of airborne pathogens.

“…The analysis of the pH‐dependent speciation of potassium ferrate(VI) suggested that the effectiveness of the HFeO 4 and H 2 FeO 4 species were, respectively, 8 and 1,935 times higher than the

{FeO}_{4}^{2 ‐}

species in MS2 inactivation. The study also found that IAOM had a greater impact than EAOM on MS2 inactivation kinetics implying that IAOM might have consumed potassium ferrate(VI) at a higher rate than EAOM (Wu et al, 2019).…”

“…Wu, Tang, Bi, Nguyen, and Yuan (2019) studied the MS2 phage inactivation kinetics by potassium ferrate(VI) at various pH conditions in the presence or absence of algae related extracellular and intracellular algal organic matter (EAOM and IAOM, respectively). The analysis of the pH‐dependent speciation of potassium ferrate(VI) suggested that the effectiveness of the HFeO 4 and H 2 FeO 4 species were, respectively, 8 and 1,935 times higher than the

“…Ferrate is renowned for its remarkable oxidising capacity, with a reduction potential of 2.2 V under acidic conditions, which decreases to 0.7 V under basic conditions [106,107]. This elevated redox potential affords ferrate enhanced efficacy as a disinfectant when compared to ozone (2.0 V) and chlorine [108]. Notably, ferrate oxidation deactivate up to 99.9% of indigenous microbial communities [106,109], and promotes the formation of insoluble ferric hydroxide particles.…”

Increasing levels of bisphenol A (BPA), classified as an endocrine-disrupting compound, in the environment have raised concerns because of its detrimental impact on human and animal health. BPA has been detected in soil and water and even as a volatile compound in the air primarily because of improper disposal and its extensive use in the production of polycarbonate plastics and epoxy resins. This review comprehensively surveyed recent research focusing on the removal of BPA from water through physicochemical and biological treatments, covering articles published from 2002 to 2023. A range of conventional and non-conventional methods employed for BPA removal is examined, and their limitations in completely degrading BPA in water are acknowledged. Hybrid or integrated treatment systems have been explored, capitalising on the distinctive removal potential of various treatment processes. The literature spanning from 2002 to 2023 underscores the efficacy of hybrid or integrated treatment systems in yielding promising results for BPA removal from water. Furthermore, future directions for BPA removal are outlined, and advancements in treatment technologies developed over the past decade are incorporated.
