TL;DR: The adsorptive purifications of contaminated water with MOFs are discussed, in order to understand possible applications of MOFs in clean water provision and plausible adsorption or interaction mechanisms and selective adsorptions are summarized.

TL;DR: It was demonstrated that amino-functionalized Ti(IV)-based MOFs could be promising visible-light photocatalysts for the treatment of Cr(VI)-contained wastewater.

TL;DR: This review article summarizes the findings of recent literatures regarding remediation of contaminated soils/sites using surfactants as an enhancing agent and reveals the good prospect of applying surfactant-based technologies to soil remediation.

TL;DR: Experimental results have revealed that the photocatalytic activity of MIL-53(Fe) for the reduction of Cr(VI) can be drastically affected by the pH value of the reaction solution, the hole scavenger and atmosphere, which makes it a potential candidate for environmental restoration.

TL;DR: The results indicated that the removal rate of Orange II was not significantly affected by the initial pH, and it increased with the higher PMS concentration, reaction temperature, Fe-Co/SBA-15 dosage and ultrasonic power, and a plausible degradation pathway is proposed.

TL;DR: This study presents the first report on the potential of PAW for the inactivation of Staphylococcus aureus inoculated on strawberries and shows it can be a promising alternative to traditional sanitizers applied in the fresh produce industry.

TL;DR: PMS oxidation with CoMn2O4 is an efficient technique for remediation of organic contaminants in wastewater and could maintain its catalytic activity in the repeated batch experiments, and a rational mechanism was proposed.

TL;DR: GO can be used as an effective adsorbents to removal antibiotics from water and is demonstrated to be high efficiency even at low ionic strength.

TL;DR: Experimental results demonstrate that heat-activated PS oxidation could be an efficient approach for remediation of water contaminated by SMZ and related sulfonamides and propose transformation pathways of SMZ oxidation.

TL;DR: The results suggest that biodegradation and photodegradation are the most important removal pathways, whereas volatilization and sorption were solely achieved for hydrophobic compounds with a moderately high Henry's law constant values such as musk fragrances.

TL;DR: The CuFe2O4@C3N4 sample exhibited stable performance without obvious loss of catalytic activity after five successive runs, showing a promising application for the photo-oxidative degradation of environmental contaminants.

TL;DR: Investigation of the underlying mechanisms and transformation pathways of atrazine degradation by cobalt catalyzed peroxymonosulfate (Co(II)/PMS) reveals that Co(II/PMS process might be an efficient technique for remediation of groundwater contaminated by ATZ and structurally related s-triazine herbicides.

TL;DR: The results demonstrated that the GO membranes can be used as effective adsorbents for heavy metal removal from water and can be regenerated more than six times based on their adsorption/desorption cycles, with a slight loss in the advertisersorption capacity.

TL;DR: The enhanced removal of sulfamethazine (SMT) from water by physically activated biochar is reported, suggesting steam activation could potentially enhance the sorption capacities of biochars compared to conventional pyrolysis.

TL;DR: Microwave-induced chemical activation process was used to prepare an activated carbon from cocoa shell for efficient removal of two anti-inflammatories, sodium diclofenac (DFC) and nimesulide (NM), from aqueous solutions.

TL;DR: The study showed that phosphorylated nanocelluloses are highly efficient biomaterials for scavenging multiple metal ions, simultaneously, from industrial effluents.

TL;DR: The remarkable adsorption with ZIF-8 suggests a specific favorable interaction (electrostatic interaction) between the positively charged surface of Zif-8 and the negatively charged PA anions.

TL;DR: The physical recycling techniques, which efficiently separate the metallic and nonmetallic fractions of waste PCBs, offer the most promising gateways for the environmentally-benign recycling of this waste.

TL;DR: The results demonstrated that planting had an effect on the distribution of ARGs in manure-amended soil, and ARGs were detected on harvested vegetables after growing in composted soil, which had potential threat to human health.

TL;DR: The treatment of a mature landfill leachate through the application of chemical-based treatment processes in order to achieve the discharge legal limits into natural water courses presented non-toxicity but biodegradability increased.

TL;DR: The excellent reusability of the adsorbent was justified after eight consecutive sorption-elution-regeneration cycles, which suggests the high selectivity to Se(IV) ions.

TL;DR: Novel Al2O3/g-C3N4 heterojunction photocatalysts were fabricated through ultrasonic dispersion method and reveal holes (h(+)) and superoxide anion radical (O2(-)) are the main active species responsible for the degradation of RhB.

TL;DR: It was found that solutions containing 24 ppm U(VI) could be completely cleaned up by ZVI-nps, regardless of the presence of NaHCO3, humic acid, mimic groundwater constituents or the change of solution pH from 5 to 9, manifesting the promising potential of this reactive material in permeable reactive barrier (PRB) to remediate uranium-contaminated groundwater.

TL;DR: Experimental results showed that AHPS was quickly oxidized by hydroxyl radicals produced simultaneously both on BDD surface by water discharge and in solution bulk from electrochemical assisted Fenton's reaction with a pseudo-first-order reaction.

TL;DR: The intermediates formed during the decomposition process were isolated, identified, and characterized using high performance liquid chromatography-photodiode array-electrospray ionization-mass spectrometry to elucidate the CV decomposition mechanism.

TL;DR: X-ray diffraction and Fourier transform infrared spectroscopy indicated that the adsorption of Cd(II) by LDHs occurred mainly via CdCO3 precipitation, surface ads orption and surface complexation.

TL;DR: Which biochar would be the most advantageous in this system would require a cost-benefit analysis between increasing crop yield and decreasing the PAH and PTE uptake, and best achieved with 5% PNBC amendments.

TL;DR: The reverse osmosis concentrate, after a nanofiltration, containing the low-molecular-weight compounds, was further treated with resin adsorption/desorption, for the recovery of phenols and their separation from carbohydrates.
