Determination of cobalt in urine by FI-ICP-AES with online preconcentration.
A method for the preconcentration and determination of cobalt in human urine samples was developed. The online preconcentration and determination were attained using inductively coupled plasma atomic emission spectromety (ICP-AES) coupled to a flow injection (FI) method. Cobalt was retained on an Amberlite XAD-7 resin as cobalt-2-(5-bromo-2-pyridylazo)-5-diethylaminophenol complex at pH 9.5. Co...
متن کاملDetermination of cadmium in water by ICP-AES with on-line adsorption preconcentration using DPTH-gel and TS-gel microcolumns.
Two flow injection inductively coupled plasma atomic emission spectrometric methods for the preconcentration and determination of trace amounts of cadmium in sea-water and waste-water samples are described based on the adsorption of the metal ion on a micro-column placed in the injection valve of the FI manifold and packed with silica gel funtionalised with 1,5-bis(di-2-pyridyl) methylene thioc...
متن کاملAutomatic on line preconcentration and determination of lead in water by ICP-AES using a TS-microcolumn.
A simple, sensitive, low-cost and rapid, flow injection system for the on-line preconcentration of lead by sorption on a microcolumn packed with silica gel funtionalized with methylthiosalicylate (TS-gel) was developped. The metal is directly retained on the sorbent column and subsequently then eluted from it by EDTA. Five variables (sample flow rate, eluent flow rate, eluent concentration, pH ...
متن کاملDetermination of molybdenum in steel samples by ICP-AES after separation and preconcentration using nanometre-sized titanium dioxide
A sensitive and selective method has been developed for the determination of Mo in steel samples using a nanometre-sized titanium dioxide micro-column (20 mm 6 3.0 mm id) and inductively coupled plasma atomic emission spectrometry (ICP-AES). Under the optimized conditions (pH 1.0, flow rate 1.5 mL min), Mo was retained on the column and separated from the iron matrix, then eluted with 0.5 mol L...
متن کاملDetermination of Cobalt in Food, Environmental and Water Samples with Preconcentration by Dispersive Liquid-Liquid Microextraction
A new method for the determination of cobalt was developed by dispersive liquid-liquid microextraction preconcentration and flame atomic absorption spectrometry. In the proposed approach, 1,5-bis(di-2-pyridyl) methylene thiocarbohydrazide (DPTH) was used as a chelating agent, and chloroform and ethanol were selected as extraction and dispersive solvents. Some factors influencing the extraction ...
