Solid phase extraction of halogenated, organophosphorus and nitrogen-containing pesticides from river water samples. Analytical quality parameters
(1999)
A study of matrix effects arising from river water samples using C18 SPE columns in the determination of 38 pesticides having different chemical properties is presented. Recoveries from river water samples of different ...
An SPME-GC-MS method for determination of organochlorine pesticide residues in medicinal plant infusions
(ViewegWiesbadenAlemanha, 2005)
Development and validation of a reversed-phase high-performance liquid chromatographic method with solid-phase extraction for the quantification of hydrochlorothiazide in ex vivo permeation studies
(John Wiley & Sons Ltd, 2017-08-01)
Hydrochlorothiazide (HCT) is a diuretic used to treat hypertension. In order to study its intestinal permeation behavior applying an ex vivo methodology, a rapid, sensitive and selective reversed-phase liquid chromatography ...
Pré-concentração de cádmio com Saccharomyces cerevisiae e determinação em águas fluviais usando espectrometria de emissão óptica com plasma indutivamente acoplado
(Sociedade Brasileira de Química, 2007-04-01)
A preconcentration method based on the use of Saccharomyces cerevisiae as sorbent material is proposed for the determination of Cd(II) in river water. The solid phase extraction was performed in batch mode and the determination ...
Rotating disk sorbent extraction for pre-concentration of chromogenic organic compounds and direct determination by solid phase spectrophotometry
(2011)
A novel and very simple microextraction approach for pre-concentration and direct solid phase spectrophotometric measurement has been developed for the determination of chromogenic analytes. The model analyte to assess ...
Quantitative separation of zinc traces from cadmium matrices by solid-phase extraction with polyurethane foam
(1998)
A system for separation of zinc traces from large amounts of cadmium is proposed in this paper. It is based on the solid-phase extraction of the zinc in the form of thiocyanate complexes by the polyurethane foam. The ...
Quantitative separation of zinc traces from cadmium matrices by solid-phase extraction with polyurethane foam
(Talanta, 1998)
A system for separation of zinc traces from large amounts of cadmium is proposed in this paper. It is based on the solid-phase extraction of the zinc in the form of thiocyanate complexes by the polyurethane foam. The ...
