Determination of vanadium and molybdenum by atomic-absorption spectrophotometry
Talanta, 1973A method is described for the determination by atomic-absorption spectrophotometry of vanadium and molybdenum, up to the milligram level, in samples of yellow cake, uranium-bearing minerals and geochemical standards. After attack with acids these two elements are separated from each other and from matrix elements by means of anion-exchange in 6M ...

Application of photon-counting in atomic-absorption spectrophotometry
Talanta, 1972An analysis is given of the statistics of photon-counting as a means of making measurements in atomic-absorption spectrometry. It is concluded that the simple application of Poisson counting statistics may give an over-optimistic estimate of the error, since other sources of error, such as flame flicker and variable nebulization rate, may be more ...

Determination of zinc by flameless atomic absorption spectrophotometry
Analytical Biochemistry, 1973Abstract The flameless atomic absorption method described here is a simple, rapid, accurate microtechnique for determining zinc in aqueous solutions, serum, or urine. It requires no sample pretreatment, only 1.0 μl of sample per determination, no correction for viscosity differences between sample and standard solutions, and is not subject to ionic ...

Determination of chromium in feces by atomic absorption spectrophotometry
Clinica Chimica Acta, 1974Abstract A new method for the determination of chromium (Cr) which is used as a continuous fecal marker for metabolic balance studies is presented. Specimens are processed in triplicate, treated with 2% ammonium chloride, and the concentration of Cr is read off in an atomic absorption spectrophotometer (AAS). The method yields excellent results, e.g.
