Polarized Zeeman-effect flameless atomic absorption spectrometry of cadmium, copper, lead, and manganese in human kidney cortex.
We used polarized Zeeman-effect flameless atomic absorption spectroscopy to quantitatively measure cadmium, copper, lead, and manganese in a nitric acid digest of lyophilized human kidney cortex. Within-run coefficients of variation for cadmium, copper, lead, and manganese, 15.3, 177.2, 84.2, and 56.3 microgram/L, respectively, were 4.1, 6.3, 3.7, and 5.6%, respectively. Between-run coefficient...
متن کاملFlameless atomic absorption spectrophotometric determination of manganese in rat brain and other tissues.
I describe a method for determining manganese in biological tissues by flameless atomic absorption spectrophotometry, It is simple to perform and does not require prior extraction with solvents. Small tissue samples are dried for 48 h at 110 degrees C and dissolved in concentrated nitric acid; the clear acid solution is introduced into the furnace and the sequential drying (120 degrees C, 20 s)...
متن کاملDetermination of urinary manganese by the direct chelation-extraction method and flameless atomic absorption spectrophotometry.
The direct chelation-extraction method, originally developed by Hessel (1968) for blood lead analysis, has been successfully applied to urinalysis for manganese. The analyses of 35 urine samples containing up to 100 microgram/1 of manganese from manganese-exposed workers showed that the data obtained by this method agree well with those by wet digestion-flame atomic absorption spectrophotometry...
متن کاملQuantification of strontium in plasma and urine with flameless atomic absorption spectrometry.
This analytical method for determination of Sr in plasma and urine involves flameless atomic absorption spectrophotometry (FAAS). Drying, charring, and atomization were optimized with respect to temperature, temperature ramp, and duration for Sr in dilute HNO3 and Sr in plasma diluted 20-fold with dilute HNO3. Calibration curves (r greater than 0.995) were linear in the concentration range 5-25...
متن کاملDetermination of diethyllead in the urine by flameless atomic absorption spectrometry.
A method for the determination of diethyllead in urine by flameless atomic absorption spectrometry after chelation with glyoxal-bis (2-hydroxyanil) and extraction of the formed complex with methyl isobutyl ketone is described. The method is specific in relation to both triethyllead and inorganic lead. The limit of detection was 3.2 micrograms Pb/l and the relative standard deviation in the conc...
