Paper-based diffusive gradients in thin films technique coupled to energy dispersive X-ray fluorescence spectrometry for the determination of labile Mn, Co, Ni, Cu, Zn and Pb in river water
(Spectrochimica Acta Part B-atomic Spectroscopy, 2012-05-01) [Artigo]
The diffusive gradients in thin films (DGT) technique has shown enormous potential for labile metal monitoring in fresh water due to the preconcentration, time-integrated, matrix interference removal and speciation analytical ...
Determination of labile barium in petroleum-produced formation water using paper-based DGT samplers
(Talanta, 2012-10-15) [Artigo]
A polyacrylamide hydrogel containing the Chelex-100 resin has traditionally been used as the binding agent for the diffusion gradients in thin films (DGT) technique. The Chelex-100 resin, although important for the ...
