Kinetic mixture effects in diffusion gradients in thin films (DGT).
The penetration of complexes into the resin domain of the DGT devices has a large influence on the lability degree of these complexes, since the reaction layer (the layer where there is net dissociation) extends from the diffusive gel into the resin domain. Numerical simulation shows that, typically, the contribution to the metal accumulation from dissociation of complexes inside the resin doma...
متن کاملIn situ speciation measurements . Using diffusive gradients in thin films ( DGT ) to determine inorganically and organically complexed metals *
The possibilities of using diffusive gradients in thin films (DGT) and anodic stripping voltammetry (ASV) to perform speciation measurements in natural waters are discussed. Both techniques measure labile species, but different approaches have been used to discriminate organic (Corg) and inorganic (Cinorg) metal complexes. In DGT, metals are bound to a resin after passing through a hydrogel tha...

متن کاملUse of diffusive gradients in thin films (DGT) in undisturbed field soils.
The technique of diffusive gradients in thin films (DGT) has been shown to be a promising tool to assess metal bioavailability in soils under laboratory conditions. In this study we used DGT to investigate the resupply kinetics of Cu and Zn under in-situ conditions in a polluted lysimeter soil and compared the results with laboratory measurements using undisturbed soil cores at defined water co...
متن کاملThe Diffusive Gradients in Thin Films Technique (DGT) for Trace Metals versus Active Sampling
The diffusive gradient in thin films (DGT) technique is an in situ passive sampling method that is designed to accumulate labile metal species in environmental systems. DGTs were applied for the determination of time integrated concentrations of low level dissolved metals in waters in areas of ecological concern. The data revealed heavy metal contamination of waters and tracked the contaminatio...
