Multielemental evaluation of garbage bags by EDXRF
(International Journal Of Environmental Analytical Chemistry, 2014-09-02) [Artigo]
Garbage bags have been broadly used for collecting household waste in Brazil and worldwide. Many of these bags are made from recycled polymers, and the presence of harmful elements is a matter of concern. In this study, ...
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 ...
Determination of labile inorganic and organic species of Al and Cu in river waters using the diffusive gradients in thin films technique
(Analytical and Bioanalytical Chemistry, 2011-03-01) [Artigo]
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 ...
