The adsorbed complex was then desorbed using 15 mL of 4.5 mol [dm.sup.-3] sulphuric acid and visible spectrophotometry as well as atomic absorption spectrophotometry analyzed the chromium content.
In this approach superficial minerals are leached from teeth and Pb is determined by electrothermal atomic absorption spectrophotometry. One important drawback to this approach is that, because an accumulation gradient for Pb has not yet been established for enamel, only biopsies of a given depth can be compared to one another.
Atomic absorption spectrophotometry revealed the presence of considerable amounts of magnesium in the extracts (Sun et al., 2003).
Laboratory analyses to determine Cd concentrations for the 1988 and 1989 samples were done using flame atomic absorption spectrophotometry (the Cd detection limit for these early samples was undocumented).
Using atomic absorption spectrophotometry, zinc was found to be the only significant component of the 1.3% ash content in this compound.
She was involved in the analyses of geological samples for metals employing classical wet assay techniques and atomic absorption spectrophotometry. She was also responsible for environmental testing on mine wastes and she was involved in the analyses of coal shipment samples employing ASTM methods.
A lthough atomic absorption spectrophotometry is a mature technique, several recent improvements make it worth another look.
Calibration standards series was prepared for each element by serial dilution of certified calibration standards for atomic absorption spectrophotometry. The instrument was optimized for lamp alignment, fuel-oxidant ratio, wavelength, and flame height.
