چکیده

aluminium determination was carried out in serum and dialysis fluid by a simple and reliable method of nameless atomic absorption with graphite furnace . . no preparatory procedures are required for water and dialysis fluid. in this method serum was mixed with 0.2% hno, to allow complete combustion of the samples in order to improve analytical precision. the method has a sensitivity of 15 pg and detection limit of 2.1 µg ai/l. the aluminium contents of the main water supply, be-distilled water and dialysis fluid were 52, i, and 44 µg/l respectively. the mean value for normal serum aluminium in isfahan was 3.6 µg/l. serum aluminium concentration in chronic renal failure was measured in pre- and post-dialysis samples. the mean values for the serum aluminium levels pre- and post-dialysis were 30.5 and 71.08 µg/l with a range of 9-60 and 21-123 µg/l, respectively. pre- and post-dialysis serum aluminium values in female patients were within the range of 1-42 and 12- 66 µg/l with mean values of 18.25 and 40.5 µg/l, respectively. instrumental settings and sample handling are discussed.

Direct determination of zinc in serum by Zeeman atomic absorption spectrometry with a graphite furnace.

We developed a precise and accurate graphite furnace atomic absorption spectrometric method for the direct determination of zinc in serum. Serum samples are analyzed after 20-fold dilution with water of ultrapure analytical grade. No other reagent is used, from the moment of sampling until measurement. During atomization, the argon flow is kept at 150 mL/min instead of gas stop, to decrease the...

Utilization of electrodeposition on a graphite probe modified with palladium in determination of lead by graphite furnace atomic absorption spectrometry in water and environmental samples

In this work a rapid and selective procedure for separation and preconcentration of lead(Pb2+) before determination by electrothermal atomic absorption spectrometry (ETAAS) wasdeveloped. The procedure is based on the electrodeposition on a graphite probe modified withpalladium. The lead was deposited from acetate buffer solution at pH 5.5. Various parameters,such as pH of solutions, deposition ...

Micromethod for lead determination in whole blood by atomic absorption, with use of the graphite furnace.

I describe a micro-scale method for determining lead in whole blood by utilizing a graphite furnace. Sample pretreatment consists of fivefold dilution with a dilute surfactant. The method is directly calibrated with lead standards prepared in dilute HNO3. To eliminate a small, nonspecific absorption signal from the blood matrix, simultaneous background correction is used. Interlaboratory co...
