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...

Development of ultrasound-assisted emulsification microextraction for the determination of trace zinc and copper by flame atomic absorption spectrometry

In this work, we developed a method based on ultrasound-assisted emulsification microextraction (USAEME) for the determination of zinc and copper by flame atomic absorption spectrometry (FAAS). The method is based on the use of the organic solvent carbon tetrachloride (CCl4) as an extraction solvent. In order to obtain a high enrichment factor, the effect of different parameters affecting the c...

Metastable aqueous foams and flame atomic absorption spectrometry.

Using calmagite as the compleximetric agent in spectro-photometric measurements of magnesium in serum involves a nonspecific matrix effect, which may bias results by as much as 25 to 30% if aqueous standards are used in serum assays. We have overcome this effect by simply adding 5 pL of the amphoteric detergent Empigen BB (300 g/L; Albright and Wilson Ltd., Whitehaven, U.K.) to each reaction cu...

Comparison of Modified Palladium Nanoparticles and Homemade Activated Carbon Derived from Medlar for Solid Phase Extraction of Metal Ions Prior to Their Flame Atomic Absorption Spectrometry Determination

This study focus on the preparation of two supports including activated carbon derived from medlar and Palladium nanoparticles loaded on activated carbon (Pd-NP-AC). Subsequently, both adsorbent modified with a novel Schiff base chelating agent and their potential applicability for determination of trace amounts of metal ions from aqueous solution has been investigated. The method is based on c...

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...
