[Determination of zinc in very small body hair samples by one-drop flame atomic absorption spectrophotometry].
A method for determination of zinc contents in very small samples of hair was developed in order to estimate the zinc concentration in the human body. All steps from weighing of samples to ashing and preparation of the test solution were done in a tube designed by us to prevent contamination and to improve handling. Zinc concentration was determined with flame atomic absorption spectrophotometr...
متن کاملExtraction 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 کاملMetastable 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...
متن کاملDispersive Liquid-Liquid Microextraction Based on Solidification of Floating Organic Drop Combined with Flame Atomic Absorption Spectrometry for Preconcentration and Determination of Thallium(III) in Water Samples
Dispersive Liquid-Liquid MicroExtraction technique based on Solidification of a Floating Organic drop (DLLME-SFO) combined with flame atomic absorption spectrometry was developed for determination of thallium in water sample. An appropriate mixture of acetone and 1-undecanol was rapidly injected into an aqueous sample containing TlCl4- which forms an ion pair with bril...
متن کاملDispersive liquid–liquid microextraction based on solidification of floating organic drop combined with flame atomic absorption spectrometry for determination trace amount of cobalt in water samples
An efficient, rapid, simple, and highly selective dispersive liquid–liquid microextraction basedon solidification of floating organic drop (DLLME-SFOD), combined with flame atomicabsorption spectrometry was developed for preconcentration and determination of trace amountsof cobalt in water samples. In this method, an appropriate mixture of acetone and1-undecanol was injected rapidly into the aq...
