[Determination of bismuth in blood urine and cerebrospinal fluid by flameless atomic absorption spectrophotometry (author's transl)].
A method for the determination of bismuth in blood, urine and cerebrospinal fluid is described. Using ammonium pyrrolidine dithiocarbamate as chelating agent, bismuth is extracted in hexane and determined by flameless atomic absorption spectrophotometry with a graphite furnace. A sample of 0.5 ml is sufficient for the determination of bismuth at concentrations ranging from a few mug/l to 2000 mug/l. In subjects not receiving bismuth, the concentration in blood is below 10 mug/l and in subjects intoxicated with bismuth prescribed for digestive diseases the concentration can reach 2000 mug/l and more.
