Ion 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...
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...
