Abstract
Influences of atomization temperatures on the characteristic mass and
the atomic absorption coefficient of chromium were studied. The experi
mental results show that the values of characteristic mass have appear
ed to be stable to better than 10% when the analyte is atomized in the
range of 2500-2800-degrees. The standardless analysis was applied to
the determination of chromium in standard sediment and geochemical ref
erence samples and satisfactory results were obtained.
