TL;DR: Surface-bound, rather than free radicals generated by a surface catalyzed-redox cycle involving both Fe(III) and Cu(II), are postulated to be responsible for the mineralization of bisphenol A.

TL;DR: It was found that most of the heavy metals existed in the oxizable and residual forms after pyrolysis, resulting in a significant reduction in their bioavailability, leading to a very low environmental risk of the biochar.

TL;DR: Based on the findings, phytofiltration (rhizofiltration) is the sole method which defined as heavy metals removal from water by aquatic plants, and free-floating plants were more efficient to uptake heavy metals in comparison with submerged and emergent plants.

TL;DR: This study provides a theoretical basis for industrial-scale recycling resources from spent LIBs by using oxygen-free roasting and wet magnetic separation to in situ recycle of cobalt, Lithium Carbonate and Graphite from mixed electrode materials.

TL;DR: It is believed the CoFe2O4/TNTs hybrid can be an efficient and green heterogeneous catalyst for the degradation of organic pollutants, and this study provides insights into the rational design and development of alternative catalysts for wastewater treatment.

TL;DR: Main advantages and drawbacks as well as target pollutant removal mechanisms are reviewed and compared, and promising integrated treatments, particularly the use of a selective adsorption step of target pollutants and the combination of advanced oxidation processes with biological treatments, are discussed.

TL;DR: From this review, the scientific community will obtain an understanding of the current state of ADS and ADN, their importance, and some encouragement and insight to take the research knowledge base to a higher level.

TL;DR: This paper reviews the route of Hg exposure to humans, its human health impacts, the associated risk assessment, and treatment based on the recent findings from various studies.

TL;DR: It is elucidated that encapsulation of nanocrystals in nitrogen-doped carbon nanotubes was an effective strategy to enhance the overall catalytic activity.

TL;DR: The adsorption behavior of different emerging contaminants on five types of multi-walled carbon nanotubes (MWCNTs), and the underlying factors were studied, found MWCNT-10 was found to be the strongest adsorbent in this study.

TL;DR: This introductory paper for the Virtual Thematic Issue on Emerging Contaminants presents a brief literature overview on key research milestones in the area of emerging contaminants, focusing on pharmaceuticals and personal care products and endocrine disrupting compounds, and highlighting selected research papers previously published in the Journal of Hazardous Materials during the period of January 2012 to December 2015.

TL;DR: This research provided an easy method to prepare ultrafine magnetic adsorbents for the effective removal of typical pharmaceuticals from water or wastewater and degrade them using ball milling.

TL;DR: This paper reviews current knowledge of the reproductive toxicity of microcystins, with regard to mammals, fishes, amphibians, and birds, mostly in males and summarizes the current research gaps.

TL;DR: A-HNTs@PVDF membrane exhibited excellent rejection stability and reuse performances after several times fouling and washing tests, and will provide insight into a new method for membrane modification in the field of wastewater treatment.

TL;DR: It is suggested that UV-254nm/PS is a promising treatment technology for the control of water pollution caused by emerging contaminants such as OTC.

TL;DR: The use of microalgae was proved to be relevant for increasing the biodegrades removal efficiency of ibuprofen by 40% and reducing the lag phase of caffeine by 3 days, and the enantioselective biodegradation of S-ib uprofen suggested a biotic prevalent removal process, which was supported by the identification of carboxy-ibUprofen and hydroxy-ib Uprofen.

TL;DR: The findings suggest that the ions release and their contributions to the NPs' toxicity should be considered in the toxicity evaluations of the metal oxide NPs.

TL;DR: Co recovery via the ammoniacal leaching is believed to gain a competitive edge on convenitonal acid leaching both by reducing the sodium hydroxide expense for increasing the pH of leaching solution and by removing the separation steps of Mn and Al.

TL;DR: A novel method that uses the aqueous sodium alginate solution for direct gelation with metal ions is developed for effective removal and recovery of heavy metals from industrial wastewater and chemical analysis of the gels suggests that the gelation mainly occurred between the metal ions and the -COO(-) and -OH groups on alginates.

TL;DR: This review summarises the methods currently available to extract radioactive actinide elements from solutions of spent nuclear fuel, and several separation methods for selective removal of these actinides from spentnuclear fuel will be described.

TL;DR: The results suggest that both composites could be used as an efficient adsorbent for the removal of lead from contaminated water sources.

TL;DR: The results of the batch experiments indicated that an increase in the catalyst dose and solution pH could enhance BPA degradation in the coupled Mn-MGO/PMS system and a possible mechanism of catalytic PMS activation was proposed.

TL;DR: In this study, a kind of high-efficiency and low-cost biochar-supported zero-valent iron nanoparticles (nZVI@BC) was synthesised and used in the remediation of Cr(VI)-contaminated soil and showed that exchangeable Cr was almost completely converted to Fe-Mn oxides and organic matter.

TL;DR: Kinetic study showed that the PEI grafting increased the initial adsorption rate of the TOCN-PEI compared with the adsorbents without PEI, and the kinetics curve suited the pseudo-second-order model better and the equilibrium data well fitted the Langmuir model.

TL;DR: The coupling process suggested that the membrane architecture could be efficiently used for treating metal solutions with low concentrations and transmembrane pressures.

TL;DR: Experimental results showed that the stability of catalyst was significantly improved when ultrasound was employed, and the toxicity of the solution increased during the first 60 min and then decreased as the oxidation proceeded.

TL;DR: Identification of transformation products showed that HA could inhibit the oxidation pathways initiated by OH during photocatalysis of TC, and provide further insights into the assessment of photolysis and photoc atalysis for antibiotics elimination in natural waters where HA exists ubiquitously.

TL;DR: It was found that the degradation of poorly soluble NOF can be strongly enhanced with the addition of TX100, and the adsorbed NOF on the catalyst was completely degraded after 2h irradiation.

TL;DR: The succession of the bacterial community appeared to have a greater influence on the variation of ARGs during composting than the presence of antibiotics, and thus the compost product should be considered as an important reservoir for ARGs.

TL;DR: The Cr(VI) reduction experiments show that the hydroxyl content of Fe2O3 samples exacts great influence on the photocatalytic activity under visible light irradiation and that the Fe2 O3 sample synthesized in n-butyl alcohol exhibits the optimal photocatallytic activity.
