Determination of cadmium in urine by graphite-furnace atomic absorption spectroscopy.
A simple procedure for graphite-furnace atomic absorption analysis of cadmium in urine, based on the use of a temperature-controlled heating unit, is described. The temperature of the carbon rod is measured by resistance and controlled by electronic feedback. We studied the influence of various heating times and temperatures of ashing and atomization, as well as suitable diluents. Urine samples...

متن کاملGRAPHITE FURNACE ATOMIC ABSORPTION SPECTROMETRY WITH MAlIlRIX MODIFICATION FOR DETERMINATION OF LEAD IN DRINKING WATER
An amoniumvanadate plus sodium molybdate mixed modifier Graphite Furnace Atomic Absorption Spectrometric method has been developed for determination of traces of lead in drinking water. The concentration of lead in the sample is obtained by direct comparison to linear working graph prepared from aqueous standards in the modifier medium, The results indicate the better performance of the pro...
متن کاملDetermination of oxaliplatin in human plasma and plasma ultrafiltrate by graphite-furnace atomic-absorption spectrometry.
A method for sensitive determination of the anti-cancer agent oxaliplatin in human plasma and human plasma ultrafiltrate (pUF) is presented. The method is based on the quantification of platinum by graphite-furnace atomic-absorption spectrometry, with Zeeman correction and an atomisation temperature of 2,700 degrees C. Sample pretreatment involves dilution of the samples with a solution contain...
متن کاملDirect Determination of Tin in Human Hair by Graphite Furnace Atomic Absorption Spectrometry Using Air Ashing in Graphite Tube
Direct determination of tin in human hair was performed by graphite furnace atomic absorption spectrometry. Human hair was cut into 3-5 mm long and 1-2 mg of the sample was directly introduced into a pyrolytically coated graphite tube, of which the injection hole was enlarged to a diameter of approximately 5 mm. After introduction of the sample, 20 μl of 30 mg Pd/l in 1 mol/l HCl was added as a...
