Abstract The authors conducted column experiments and a modeling study to understand the effects of several environmental factors on aggregation transport graphene oxide nanoparticles (GONPs) in saturated quartz sand. GONPs were negatively charged stable under test conditions (0–50 mM NaCl; pH 4.8–9.0), Derjaguin–Landau–Verwey–Overbeek (DLVO) calculation indicated that deposition was unfavorable attachment conditions. exhibited high mobility even at an ionic strength 25 NaCl. insensitive...
Eutrophication caused by excessive phosphate discharge into surface water has raised wide concern, and the efficient removal of phosphates from wastewater using sorption methods is very important. In our study, magnetite particles with two different sizes characteristics were chosen as sorbents to examine their adsorption desorption behavior toward phosphate. Scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) N2 adsorption-desorption used characterize morphological...
Salinity reduces agricultural productivity majorly by inhibiting seed germination. Exogenous salicylic acid (SA) can prevent the harm caused to rice salinity, but mechanisms which it promotes germination under salt stress are unclear. In this study, inhibition of in salt-sensitive Nipponbare was greater than that salt-tolerant Huaidao 5. Treatment with exogenous SA significantly improved Nipponbare, had little effect on The effects ion balance, metabolism reactive oxygen species (ROS),...
In recent years, freshwater resource contamination by non-point source pollution has become particularly prominent in China. To control (NPS) pollution, it is important to estimate NPS exports, identify sources of and analyze the characteristics. As such, this study, we established modified export coefficient model based on rainfall terrain investigate characteristics total nitrogen (TN) phosphorus (TP) throughout Huangqian Reservoir watershed—which serves as an potable water for main...
Understanding subsurface transport of fullerene nanoparticles (nC(60)) is critical importance for the benign use and risk management C(60). We examined effects several important environmental factors on nC(60) in saturated porous media. Decreasing flow velocity from approximately 10 to 1 m/d had little effect Ottawa sand (mainly pure quartz), but significantly inhibited Lula soil (a sandy, low-organic-matter soil). The difference was attributable smaller grain size, more irregular rougher...
With the increasing production and use of graphene oxide, environmental implications this new carbonaceous nanomaterial have received much attention. In study, we found that presence low concentrations oxide nanoparticles (GONPs) significantly enhanced transport 1-naphthol in a saturated soil, but affected phenanthrene to smaller extent. The stronger transport-enhancement effect on was due significant desorption hysteresis (both thermodynamically irreversible adsorption slow kinetics)...
Bisphenol A (BPA) is a typical endocrine-disrupting chemical. The removal of BPA has raised much concerns in recent years. This paper examined the adsorption behavior to biochars and different effects cationic, anionic, nonionic surfactants. results indicated that peanut shell prepared at 300°C (BC300), 500°C (BC500), 700°C (BC700) showed strong affinity for BPA, increased with increase pyrolysis temperature. range log K d values was 2.83∼3.71, 2.91∼4.57, 3.24∼5.50 BC300, BC500, BC700,...
Carbon nanotubes (CNTs) can exist in the form of colloidal suspension aquatic environments, particularly presence natural organic matter or surfactants, and may significantly affect fate transport contaminants. In present study, authors examined adsorption phenanthrene, 2-naphthol, 1-naphthylamine to three CNTs, including a stable oxidized multiwalled carbon (O-MWNT), humic acid (HA)-modified O-MWNT, sodium dodecyl sulfate (SDS)-modified O-MWNT. All O-MWNTs exhibit strong affinities test...
Abstract The authors observed that humic acid (HA) mediates transport of tetracycline and pyrene in saturated porous media via distinctively different mechanisms. presence HA (20–80 mg C/L) the influent consistently enhances tetracycline, whereas for a critical concentration exists (about 10 C/L), below which is inhibited but above enhanced. difference effect stems from relative sorption affinity to sand between these two compounds. Because driven primarily by hydrophobic effect, exhibits...
The natural runoff mechanism of the Dawen River, main tributary lower Yellow has been stressed in recent years as a result human activity, and hydrological situation changed dramatically. In this paper, various statistical methods such Mann–Kendall nonparametric test, cumulative anomaly, ordered clustering, sliding T rainfall–runoff double-cumulative curve were used to study evolution characteristics factors River. revealed that rainfall River decreased overall from 1956 2016, but downward...
Hydropower operations significantly alter the natural hydrological conditions of rivers, exerting adverse effects on riverine ecosystems. Accurate identification fish habitats under hydropower operation and maintaining suitable ecological flow are crucial for conservation water resource management. Coreius guichenoti was selected as target species Yibin reach downstream Jinsha River studied river reach. Subsequently, Weighted Usable Area (WUA) Habitat Connectivity Index (HCI) were employed...
