Solar-driven sorption-based atmospheric water harvesting (SAWH) is an emerging freshwater production technology for alleviating increasing scarcity. However, existing vapor sorbents typically suffer from environmentally unfriendly synthesis processes or components. The development of efficient SAWH that are compatible highly demanded but remains a challenge. Herein, novel, eco-friendly, and degradable biomass-based sorbent developed the solar-driven via green approach by integrating...
To improve the main shortcomings of insufficient nutrients, high salinity and low productivity in saline-alkali soils, this study collected soil samples from Da'an City Baicheng sediment adjacent Qianguo irrigation district, measured their pH values major element contents, designed verified improvement scheme based on geochemical engineering principles. Results indicated that value various contents could be adjusted by adding to make it close reference soil. Both theoretical calculation...
Contaminants of Emerging Concern (CECs), including per- and polyfluoroalkyl substances (PFASs) organophosphate flame retardants (OPFRs), have raised global concerns due to their persistence, bioaccumulation potential, toxicity. This study presents a comprehensive investigation the occurrence, spatiotemporal distribution, potential sources, ecological human health risks associated with 18 PFASs 9 OPFRs in surface waters upper Yangtze River, China. The water samples were collected from main...
A new mixed eluent (EDDS + FeCl<sub>3</sub>) was successfully designed and applied for the remediation of multiple heavy metal pollution in soil.
The rational utilization of solid waste has always been a worldwide concern. In this study, coal fly ash (CFA) and red mud (RM) were used in combination to synthesize efficient heavy metal adsorbents. A new way resource recycling was provided with the collaborative reuse CFA RM. To obtain modified composite materials, RM mixed melted three ratios. After modification, these materials then utilized adsorb Pb, Cu, Cd water both single ternary systems. physicochemical properties CFA, RM,...
The huge annual output of coal fly ash is harmful to the environment, but it widely used because its good adsorption potential. In this study, using as a raw material and sodium hydroxide an activator, novel adsorbent was synthesized at 300 °C adsorb low concentrations ammonia nitrogen from water. scanning electron microscopy, X-ray diffraction analysis, Fourier transform infrared spectroscopy, energy dispersive surface area porosity analyzer were analyze adsorbent’s physicochemical...
Abstract At present, the direct gold determination in geological samples by inductively coupled plasma mass spectrometry (ICP-MS) is still an arduous challenge due to both spectral and background interferences. It very important necessary study pretreatment processes; therefore, polyurethane foam treatment sample digestion methods are explored compared here. The experimental results showed that adsorption rate of treated was significantly improved as impurities were cleaned up, potential...
Abstract In this paper, the vertical variations of heavy metal elements (including Cd, Cr, Cu, Hg, Mn, Ni, Pb, and Zn) in sediments Songhua Lake are analyzed using sediment cores. A 70‐year evolutionary history these is described sources metals investigated by evaluating pollution characteristics terms their enrichment coefficients geoaccumulation indexes. The results indicate that Zn originated mainly from basin erosion were transported to lake rivers. Cd Hg also occurred prior mid‐1990s,...
Black soils are vital agricultural resources, and assessing heavy metal contamination in black is of great significance to the sustainable development agriculture environment. In this study, 1246 surface soil samples were collected from central-eastern part Changchun, where phaeozems chernozems widely distributed, As, Hg, Cr, Cd, Pb concentrations determined investigate pollution status by geoaccumulation index (Igeo). To eliminate influence background variation improve calculation accuracy...
To provide technical support and theoretical guarantee for the prevention control of soil heavy metal pollution, main types topsoil parent material in Jilin Province were systematically collected, accurately tested by atomic fluorescence spectrometry inductively coupled plasma mass spectrometry, comprehensively evaluated through five indexes. By principal component analysis, it was initially judged that there 2 or 3 major sources topsoil, which could be attributed to material, soil-forming...
This study collected 1135 topsoil samples of cultivated land in Laiyang County, eastern China, to analyze the distribution, pollution and health risks heavy metals (As, Cd, Cu, Cr, Hg, Ni, Pb Zn). The results show that: (1) levels eight at some sites were higher than risk screening values there was metal pollution. (2) An improved geoaccumulation index used evaluate soil average value Igeo before after improvement 0.32 (Iml, no medium pollution) −0.04 (Iol, pollution), respectively. (3) Hg...
To explore the existing characteristics of nitrogen and phosphorus in main rivers Changchun City, overlying water sediment were sampled tested. The results showed that spatial distribution contents was diverse. In water, north west high, while their south low. sediment, high low north. pollution serious most rivers. Xinkai River, Chuan Lake, West Lake had acutest ammonia, total nitrogen, phosphorus, contamination degree Yongchun River lowest. terms time, with government actively carrying out...
