Preconcentration and determination of palladium water samples by ionic liquid - dispersive liquid liquid microextraction combined with flame atomic absorption spectrometry
A simple, rapid and efficient dispersive liquid–liquid microextraction by use of ionic liquid (IL-DLLME)method, followed by flame atomic absorption spectrometry (FAAS) was developed for the preconcentrationand determination of palladium in water samples. In this method, an appropriate mixture of acetone and octylmethyl imidazolium hexafluorophosphate was injected rapidly into the aqueous sample...
متن کاملDetermination of Pyrethroid Pesticides in Environmental Samples using Ionic Liquid Dispersive Liquid-Liquid Microextraction
Microextração líquido-líquido dispersiva (DLLME) utilizando líquido iônico (IL) como solvente extrator foi desenvolvida com uma nova abordagem para a determinação de quatro pesticidas piretróides em amostras ambientais de água e solo. Cromatografia líquida de alto rendimento com detector de UV (HPLC-UV) foi empregada na análise cromatográfica. Este método é rápido, fácil de operar e ambientalme...

متن کاملIonic Liquid-Based Dispersive Liquid-Liquid Microextraction Combined with Flame Atomic Absorption Spectrometry for Determination of Silver in Water Samples
The widespread use of silver compounds and silvercontaining procedures in industry, medicine, jewellery, cloud seeding and in disinfection of drinking water has resulted in an increasing silver content in environmental samples. Silver impregnated filters are used in water disinfection, while silver concentrations up to 200 μg L are permitted for antimicrobial activities for human health. Silver...
متن کاملDetermination of estrogens in water samples using dispersive liquid liquid microextraction and high performance liquid chromatography.
A new method for the analysis of estrogens including estrone (E1), 17b- estradiol (E2) and diethylstilbestrol (DES) in aqueous samples was performed using dispersive liquid liquid microextraction (DLLME) and high- performance liquid chromatography (HPLC). In order to optimize DLLME some important parameters such as type and volume of extraction and disperser solvent, extraction time, ionic stre...
