Journal ArticleDOI
In-situ speciation measurements of trace components in natural waters using thin-film gels.
William Davison,Hao Zhang +1 more
TL;DR: In this paper, a simple technique for measuring trace-metal concentrations in situ in water is described, where an ion exchange resin is separated from the solution by an ion-permeable gel membrane.
Journal ArticleDOI
Performance Characteristics of Diffusion Gradients in Thin Films for the in Situ Measurement of Trace Metals in Aqueous Solution
Hao Zhang,William Davison +1 more
TL;DR: In this article, diffusive gradients in thin films (DGT) is used for quantitatively measuring labile species in aqueous systems by ensuring that transport of metal ions to an exchange resin is solely by free diffusion through a membrane, of known thickness, Δg.
Journal ArticleDOI
A new method to measure effective soil solution concentration predicts copper availability to plants
TL;DR: The quantity CE is shown to have promise as a quantitative measure of the bioavailable metal in soils, which includes both the soil solution concentration and an additional term, expressed as a concentration, that represents metal supplied from the solid phase.
Journal ArticleDOI
Diffusional characteristics of hydrogels used in DGT and DET techniques
Hao Zhang,William Davison +1 more
TL;DR: In this paper, the diffusion coefficients of trace metals and fulvic and humic substances in five different hydrogels were measured and the results were consistent with the known open structures of AGE and APA gels and the dependence of the structure of BPA gels on monomer concentration.
Journal ArticleDOI
In situ fixation of metals in soils using bauxite residue: chemical assessment
TL;DR: The results suggest that specific chemisorption, and possibly metal diffusion into oxide particles could also be the mechanisms responsible for the fixation of metals by red mud.
