Title Comparison of atomic absorption and fluorescence spectroscopic methods for the routine determination of urinary arsenic
Bibliographic information Feb. 2005, Vol.78, No.1, p.51-59. Illus. 23 ref.
Abstract The objective of this study was to develop a rapid and robust technique for the measurement of urinary inorganic arsenic. It involves the measurement of arsenic in urine after hydride generation in acid medium and uses atomic fluorescence spectrometry (AFS) as the detection system. The AFS procedure was found to be more precise and sensitive than the atomic absorption spectroscopy (AAS) technique using a quartz cell. A variation of the procedure that allows the detection of non-directly reducible arsenic forms was also validated for samples with high arsenic concentrations.
