Electrothermal atomic absorption spectrometric determination of volatile elements in biological materials in the presence of a mixed palladium-tungsten chemical modifier

Thermal stabilization of several volatile elements (antimony, arsenic, bismuth, cadmium, lead, selenium, tin, and thallium) in biol. digests, solubilized hair and dild. urine in the presence of mixed modifiers: palladium-tungsten and palladium-tungsten-ammonium nitrate (for urine) has been studied. ETAAS procedures for anal. of biol. tissues and urine have been elaborated. Simple techniques for pre-instrumental treatment and fast temp. programs are expedited. Applications to different biol. ref. materials have been demonstrated. The relative errors and RSDs are less than 10%, and the analyte recoveries are within 96 and 108%. [on SciFinder (R)]
