Determination of low levels of molybdenum (VI) in food samples and beverages by cloud point extraction coupled with flame atomic absorption spectrometry
(2013)
Cloud point extraction (CPE) was used for the preconcentration of molybdenum (Mo), after the formation of a complex with Victoria pure blue BO (VPB+) in presence of excess thiocyanate and cetylpyridinium chloride (CPC) at ...
Investigation of Pd-catalyzed Co(III)-EDTA/hypophosphite inhibition reaction kinetics, mechanism and the evaluation of its analytical application possibilities
(Serbian Chemical Society, 2004)
The reaction between Co(III)-EDTA and hypophosphite ion, catalyzed by Pd(II) was chosen as the indicator reaction. The inhibition kinetics of this catalytic reaction have been investigated by a mechanistic approach in the ...
Inexpensive and versatile method for trace Sn(II) and Sn(IV) ions in food samples by CPE/FAAS
(2012)
In this work, a new cloud point extraction procedure was developed for the separation and preconcentration of tin ions in water and food samples. The method is based on the complexation of Sn(IV) ions with calcon carboxylic ...
Kinetic spectrophotometric determination of trace amounts of selenium based on the catalytic reduction of maxilon blue-SG by sulfide
(Elsevier Inc., 2003)
A simple and sensitive catalytic spectrophotometric method was developed for the determination of trace amounts of selenium. The method is based on the catalytic effect of selenium in form Se(IV) on the reduction of Maxilon ...
Development of a cloud point extraction and preconcentration method for chromium(III) and total chromium prior to flame atomic absorption spectrometry
(2012)
A sensitive and selective method has been developed for the determination of chromium in water samples based on using cloud point extraction (CPE) preconcentration and determination by flame atomic absorption spectrometry ...
Determination of sodium and potassium in certified rock samples by AES after ultrasonic leaching
(2006)
In order to evaluate the data obtained by atomic emission spectrometric analysis after ultrasonic extraction, destructive analysis of some certified rock samples employing ultrasonic waves was applied to two elements, Na ...
A novel indicator system for catalytic spectrophotometric determination and speciation of inorganic selenium species (Se(IV), Se(VI)) at trace levels in natural lake and river water samples
(2011)
A novel catalytic kinetic method is proposed for the determination of Se(IV), Se(VI), and total inorganic selenium in water based on the catalytic effect of Se(IV) on the reduction of Celestine blue by sodium sulfide at ...
Investigation of separation and indentification possibilities of some metal-dithizonate complexes by sequential TLC-IR system
(2005)
The separation and identification possibilities of a number of metal-dithizonate complexes were investigated by means of a TLC-IR sequential system. Dithizonate complexes of some metal cations were pre-pared in a predetermined ...
Development of a cloud point extraction and preconcentration method for determination of trace aluminum in mineral waters by FAAS
(2011)
A cloud point extraction (CPE) method has been developed for the preconcentration of trace aluminum prior to its determination by flame atomic absorption spectrometry (FAAS). The CPE method is based on the complex of Al(III) ...
