“…As an increasingly mature application, nuclear power technology can even completely replace fossil fuels to meet future energy needs. − However, a large amount of nuclear wastewater will be generated during the nuclear fuel cycle process, including nuclear facility decommissioning, equipment maintenance, accident treatment, etc. , Researchers have developed various methods to remove or extract uranium ions in wastewater. − Unfortunately, this type of wastewater contains not only radioactive elements but also various organic substances, including alkyl glycosides, xanthan gum, oxalic acid, citric acid, and tannic acid (TA) . In addition, the industrial electroplating wastewater was also found to contain TA .…”

Photocatalytic technologies are expected to solve the problem of organic matter pretreatment in nuclear wastewater to realize the sustainable development for energy and environment. However, the design and synthesis of the low-cost and high-efficiency photocatalysts are a significant challenge to achieve this goal. In this work, the 2D/2D g-C 3 N 4 /1T-MoS 2 Schottky heterojunction photocatalyst was prepared by a liquid-phase ultrasonic self-assembly method, and the enhanced carrier separation ability was proved by the electrochemical impedance spectroscopy, transient photocurrent, and photoluminescence spectra, which improved the photocatalytic quantum efficiency. The results suggested that the 2D/2D g-C 3 N 4 /1T-MoS 2 heterojunction not only has a satisfactory ability to treat tannic acid in nuclear wastewater but also has excellent removal effects on various dyes including methylene blue, rhodamine B, methyl violet, amaranth, and methyl orange. This work provides an effective approach to construct the 2D/2D Schottky heterojunctions for the application in photocatalytic spent fuel wastewater or industrial sewage treatment.

“…For instance, Gu et al reported that the flower-like polyvinyl pyrrolidine intercalated MoS 2 composites displayed the high removal performance toward U(VI) (117.9 mg/g at pH 4.5, T = 298 K), compared to single MoS 2 (23.7 mg/g, Figure A) . Li et al reported that adsorption capacities of U(VI) on MoS 2 (492.72 mg/g, pH 5.5, Figure B) were significantly higher that of the other MoS 2 -based composites such as sodium-dodecyl-sulfate-modified MoS 2 composites (98.4 mg/g), chitosan-modified MoS 2 (168.98 mg/g, at pH 5.0), respectively, , a fungal hyphae-graphene-MoS 2 hybrid (275 mg/g), and poly(diethyl(4-vinylbefqnzyl)phosphonate- co -maleic anhydride) (448.4 mg/g at pH 4.0) …”

Molybdenum disulfide (MoS2), as one of the most common two-dimensional (2D) metal sulfides, has been attracting much attention in the area of energy storage and environmental remediation, because of its fascinating properties. Although much research regarding the environmental application of MoS2 have been recently summarized, reports on the recent progress of the removal of various environmental pollutants on MoS2 are still scarce. Herein, we systematically summarize the efficient elimination of environmental contaminants (e.g., gas, organic, heavy metals, and radionuclides) on MoS2-based nanosheets. In addition, the interaction mechanisms (e.g., physical (hydrogen bonding, van der Waals forces), ion-exchange, chemical adsorption, and redox) of environmental contaminants on MoS2-based materials were elucidated in detail. Finally, the major challenges and future prospective on MoS2-based materials were presented. This review has important implication for the design of MoS2-based materials with high adsorption performance and strong redox capacity toward the removal of various environmental pollutants in actual application.

“…All micro-organisms including bacteria, fungi, algae and lichens are capable of adsorbing and accumulating HMs (Kalaimurugan et al, 2020;Leong & Chang, 2020;Mosai et al, 2020;Zapana-Huarache et al, 2020). Fungi have advantages over bacterial cells that are large cell size, and are with high surface-to-volume ratio, ease of growth, high biomass yield, excellent metal tolerance capacity, high intracellular and wall metal-binding capacity, easy genetic manipulation, capability to produce extracellular enzymes, and good tolerance to adverse conditions such as high temperature and acidic or alkaline pH (Li et al, 2019). As a result of the extensive use of fungal species for commercial biogenesis, an excess of cheap fungal biomass is produced as a by-product.…”

Aims: Contamination with heavy metal (HM) is a severe environmental issue.Therefore, there is a pressing need to create environmentally safe and cost-effective HM bioremediation approaches. Methods and Results: Three iron-tolerant fungal strains were isolated from sewageirrigated soils, molecularly identified and deposited in the GenBank as Aspergillus flavus MT639638, A. terreus MT605370 and Fusarium oxysporum MT605399. The fungal growth, minimum inhibitory concentration (MIC), tolerance index (TI), removal efficiency, bioaccumulation, and enzymatic and non-enzymatic antioxidants were determined. Based on MIC values, A. flavus MT639638 was the most resistant strain. F. oxysporum displayed the highest percent removal efficiency (93.65% at 4000 mg L −1 ) followed by A. flavus (92.92%, at 11,000 mg L −1 ), and A. terreus (91.18% at 3000 mg L −1 ). F. oxysporum was selected based on its highly sensitivity for further characterization of its response to Fe(II) stress using TEM, SEM and EDX, in addition to HPLC analysis of organic acids. These analyses demonstrated the localization of bioaccumulated Fe(II) and ultrastructural changes induced by iron and indicated induction release of organic acids. Conclusions:Our fungal strains showed an effective capacity for removal of Fe(II) via bioaccumulation and biosorption mechanisms which were supported by instrumental analyses. The iron tolerance potentiality was mediated by induction of selected antioxidative enzymes and biomolecules. Significance and Impact of the Study:This study depicts a potential utilization of the three fungal strains for the bioremediation of iron-contaminated soils.
