Micro-nano composite material was prepared to adsorb Hg(II) ions via the co-precipitation method. Oyster shell (OS), Fe3O4 nanoparticles, and humic acid (HA) were used as raw materials. The adhesion of nanoparticles OS displayed by scanning electron microscopy (SEM), appearance (311) plane standard derived from X-ray diffraction (XRD), transformation pore sizes 50 nm 20 μm mercury intrusion porosimetry (MIP) jointly revealed successful grafting HA-functionalized onto oyster surface....
Estuarine sediments serve as significant reservoirs for mercury (Hg) and methylmercury(MeHg), which can also interconvert in the external environment. The release of Hg response to human activities raises concerns about its potential ecological health effects. Sediment samples were collected December 2021 from four locations (sites), cycling by measuring concentrations of, controls on, spatial distribution total (THg) methylmercury (MeHg) high-tidal zone (HTZ) mid-tidal (MTZ) a mangrove...
We analyzed the distribution characteristics of mercury speciation and chemical factors in sediment National Mangrove Reserve Zhanjiang. The results showed that Organic-bound(Hg-OXI) was most predominant both high-tide mid-tide zones, followed by residual mercury(Hg-RES). While other three mercury-bound forms iron-manganese mercury(Hg-RED), water-extractable mercury(Hg-WAT), carbonate-bound mercury(Hg-ACID), which can be converted to bioavailable according environmental changes, accounted...
Abstract The decomposition of organic matter(OM) into dissolved matter(DOM) isaccomplished by a series bacterial extracellular enzymes, which can also be affected nitrogen and phosphorus. There have been many studies on the molecular weight, source, humification characteristics, transformation OM, but fewer relationship between DOM with enzyme activity under natural total nitrogen(TN) phosphorus(TP). So we investigated TN TP concentration in offshore sediments mangrove forest oyster farm...
This study provided basic datas of environmental factors and the fractionations distribution pollutant mercury in profiles Zhanjiang mangrove forest sediments, further analyzed relationship between them. The results showed that Hg-OXI was most predominant both high-tide zone mid-tide sediments forest, correlation analysis percentages Hg-WAT, Hg-ACID Hg-RED were only correlated with pH, TOC SO42- area, which them below at 15% 6% respectively. Further research is needed future on other affect...
A simple and sensitive Pb[Formula: see text] sensor is developed based on label-free 17E DNAzyme unmodified Au nanoparticles. On this basis, concentration can be judged according to the color variation of The detection limit 100[Formula: text]nM linear range text]nM–16[Formula: text][Formula: text]M. It serve as a measurement tool for rapid detection, which provides reference development sensors in environmental monitoring food safety.
