Abstrakt

The method of direct determination of Cr by ETAAS in blood serum and whole blood after dilution with 0.1% Triton X-100 and 1% HNO3 is described. The temperature programme of graphite furnace involved careful drying at 70 oC, two-step pyrolysis at 800 and 1100 oC, and atomization at 2400 oC. No chemical modification was included, background correction was carried out by deuterium arc corrector. The detection limit was 0.24 mg.l-1 Cr. The method was used for analysis of blood serum of patients with chronic renal failure treated by heamodialysis.
