Preconcentration and speciation of chromium in water samples by atomic absorption spectrometry after cloud-point extraction.
A rapid, sensitive and accurate atomic absorption method for Cr(III) and Cr(VI) ions was developed based on the cloud-point extraction (CPE) technique. Cr(III) reacts with a new Schiff's base ligand to form the hydrophobic complex, which is subsequently entrapped in the surfactant micelles. The Cr(VI) assay is based on its reduction to Cr(III) by the addition of concentrated H2SO4 and ethanol t...
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 کاملDetermination of Trace Silver in Water Samples by Online Column Preconcentration Flame Atomic Absorption Spectrometry Using Termite Digestion Product
A new method for Ag determination in water samples using solid phase extraction (SPE) coupled to a flow injection system and flame atomic absorption spectrometry was developed. The sorbent used for Ag preconcentration and extraction was the termite digestion product. Flow and chemical variables of the system were optimized through a multivariate procedure. The factors selected were adsorbent ma...
متن کاملDetermination of lead and cadmium in water samples by cloud point extraction prior to flame atomic absorption spectrometry determination
Pb and Cd in water samples were determined by cloud point extraction (CPE) with sodiumdiethyldithiocarbamate (DDTC) as the chelating agent and octylphenoxypolyethanl (Triton X-114) asthe surfactant prior to flame atomic absorption spectrometry (FAAS) determination. The main factorsof affecting the extraction and detection processes were optimized. The preconcentration of 10 mL ofstandard soluti...
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...
