Extraction and Determination of Heavy Metals Using Silver Coated Magnetic Nanoparticles and Flame Atomic Absorption Spectrometry
A rapid, simple and sensitive magnetic solid phase extraction (MSPE) method was developed for the pre-concentration and determination of copper and cadmium ions. In this study, modified Fe3O4@Ag nanoparticles were synthesized and then ligand 2-isonicotinoyl hydrazine carbodithiolate (ITHCDT) was bonded to silver due to the formation of covalent bond of S-Ag. In this method, copper and cadmium i...
متن کاملPreconcentration 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 کاملDispersive Liquid-Liquid Microextraction of Bismuth in Various Samples and Determination by Flame Atomic Absorption Spectrometry
A dispersive liquid-liquid microextraction method for the determination of bismuth in various samples by flame atomic absorption spectrometry is described. In this method, crystal violet was used as counter positive ion for BiCl4 (-) complex ion, chloroform as extraction solvent, and ethanol as disperser solvent. The analytical parameters that may affect the extraction efficiency like acidity o...
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 کاملIon Pair Dispersive Liquid-Liquid Microextraction for the Determination of Trace Amounts of Copper(II) in Soil, Multivitamin Tablet, Tea and Water Samples Using Flame Atomic Absorption Spectrometry
Ion pair dispersive liquid- liquid microextraction (IP-DLLME) method combined with flame atomic absorption spectrometry was proposed for the determination of trace amounts of copper(II). By using pyrocatechol violet as chelating agent and cetyltrimethyl ammonium bromide as an ion pairing agent, the trace amount of copper(II) was extracted in chloroform. The factors influencing the formation cop...
