A new approach to improve the accuracy of DGT (Diffusive Gradients in Thin-films) measurements in monitoring wells
(2022-02-01)
The Diffusive Gradients in Thin-films (DGT) technique represents an ideal tool for monitoring water quality of inorganic species in systems with a high flow such as rivers, streams, lakes and seas. However, in low-flow ...
Diffusive gradients in thin films based on banana peel and moringa seeds binding gel disks for in situ measurement of Cd, Cu, Pb and Zn
(Taylor & Francis Ltd, 2020-02-23)
Novel Diffusive Gradients in Thin Films (DGT) binding agents, Musa cavendishi banana peel (BP) and Moringa Oleifera seeds (MOS) immobilised in agarose gel, have been developed and validated for the determination of Cd, Cu, ...
In situ redox speciation analysis of chromium in water by diffusive gradients in thin films using a DE81 anion exchange membrane
(2016-07-01)
A method for the in situ redox speciation analysis of chromium in water by the diffusive gradients in thin films (DGT) technique using a DE81 anion exchange membrane was successfully developed. For the selective uptake of ...
Determination of mercury in river water by diffusive gradients in thin films using P81 membrane as binding layer
(Elsevier B.V., 2014-11-01)
In this work, a device based on diffusive gradients in thin films (DGT) was evaluated for the determination of Hg(II) in river water. The DGT device was assembled with a cellulose phosphate ion exchange membrane (P81 ...

(Springer Heidelberg, 2011-03-01)
The diffusive gradients in thin films (DGT) technique, using a diffusive gel or a restrictive gel, was evaluated for the determination of labile inorganic and organic species of Al and Cu in model synthetic solutions and ...
Evaluation of diffusive gradients in thin films technique (DGT) for measuring Al, Cd, Co, Cu, Mn, Ni, and Zn in Amazonian rivers
(Springer, 2014-02-01)
Studies concerning the lability and bioavailability of trace metals have played a prominent role in the search for contamination of water resources. This work describes the first application yet of the diffusive gradients ...
Application of chitosan film as a binding phase in the diffusive gradients in thin films technique (DGT) for measurement of metal ions in aqueous solution
(2020-01-01)
Diffusive gradients in thin films technique (DGT) allows in situ determination of labile metal in water, soils, and sediments. This paper aims to evaluate the performance of a new proposal of DGT to measure Cu2+ and Cd2+ ...
