Removal and recovery of high levels arsenic (As) in copper smelting wastewater present a great environmental challenge. A novel approach was investigated for the first time using TiO2 As adsorptive removal from subsequent spent adsorbent regeneration NaOH. EXAFS results demonstrate that As(III), as only species raw water, does not form an aqueous complex with other metal ions. An average 3890 ± 142 mg/L As(III) at pH 1.4 reduced to 59 79 μg/L effluent final 7 21 successive treatment cycles...
Surface-enhanced Raman scattering (SERS) analysis of environmental hydrophobic pollutants without chemical functionalization a bare nanoparticle (NP) substrate presents challenge. The motivation for our study is to develop highly reproducible and robust portable SERS sensor detection identification polycyclic aromatic hydrocarbons (PAHs) using Au NPs. Our hypothesis that the coffee ring effect could separate PAHs from bulk solution concentrate them on closely packed NP ring, consequently...
Coexisting arsenic (As) and fluoride (F) in groundwater poses severe health risks worldwide. Highly efficient simultaneous removal of As F is therefore great urgency high priority. The purpose this study was to fabricate a novel composite adsorbent explore the mechanism for concurrent As(V) at molecular level. This bifunctional with titanium lanthanum oxides impregnated on granular activated carbon (TLAC) exhibits pronounced adsorption capacity over commercially available iron-...
A new phosphorus (P) removal and recovery process that integrates an FeCl3-dosing, membrane bioreactor (MBR), side-stream cofermentation was developed for wastewater treatment. The Fe P species their transformation mechanisms via aerobic anaerobic conditions were investigated with X-ray absorption near edge structure (XANES) spectroscopy. In the treatment system, 98.4% of total in domestic removed retained activated sludge MBR. During subsequent acidogenic food waste, MBR released eventually...
Chronic exposure to arsenic (As) threatens human health. To systematically understand the health risks induced by As ingestion, we explored water and diet contributions exposure, compared in biomarkers arsenicosis a geogenic area China. In this study, high percentages of (77% n = 131 total samples), vegetables (92%, 120), cereals (32%, 25), urine (70%, 99), nails (76%, 176), hair (62%, 61) contained higher than acceptable levels. Dietary contributed 92% average daily dose (ADD) when...
Rapid and sensitive SERS identification quantification of arsenic species in multiple matrices have been realized using a Fe3O4@Ag magnetic substrate. The molecular structure on characterized EXAFS spectroscopy DFT confirms the existence chemical effect enhancement.
Long term mining activities can cause significant metal pollution in the environment, thereby showing potential risk to paddy field. Elucidating interfacial processes of trace metals from contaminated soil rice within rhizosphere provide important information on biogeochemistry and food safety. The current study aims explore spatial distribution molecular speciation Cu plant a mining-impacted soil, reveal possible uptake mechanisms. X-ray absorption near edge structure (XANES) analysis...
Objective Gray matter loss in the limbic structures was found recent onset post traumatic stress disorder (PTSD) patients. In present study, we measured regional gray volume trauma survivors to verify hypothesis that may cause different with and without PTSD. Method High resolution T1-weighted magnetic resonance imaging (MRI) were obtained from coal mine flood disaster (n = 10) PTSD 20 no exposed normal controls. The voxel-based morphometry (VBM) method used measure three groups,...
Groundwater quality is strongly compromised by polluted surface water recharge in rapidly developing urban regions. However, gaps still remain the understanding of critical contaminants controlling and...
The transformation of Fe–P complexes in bioreactors can be important for phosphorus (P) recovery from sludge. In this research, X-ray absorption near-edge structure analysis was conducted to quantify the Fe and P species sludge different aging periods subsequent acidogenic cofermentation recovery. readily removed wastewater by Fe-facilitated coprecipitation adsorption could extracted recovered via microbial iron reduction with food waste. fresh Fe-based mainly contained ferrihydrite...
Summary The assemblage of root‐associated microorganisms plays important roles in improving their capability to adapt environmental stress. Metal(loid) hyperaccumulators exhibit disparate adaptive compared that non‐hyperaccumulators when faced with elevated contents metal(loid)s. However, knowledge the root microbes and ecological plant growth is still scarce. present study used Pteris vittata as a model microbial its beneficial role growth. We demonstrated from associated bulk soil...
