Ya. Vilpan et al., DIRECT DETERMINATION OF CADMIUM IN SOLID FOODSTUFFS BY ATOMIC-ABSORPTION ANALYSIS, Journal of analytical chemistry, 52(5), 1997, pp. 484-487
A procedure is proposed for the direct rapid determination of cadmium
in solid foodstuff samples by atomic absorption analysis using a modif
ied L'vov furnace equipped with a graphite partition filter The use of
this furnace eliminates the step of transferring a solid sample to so
lution, allows calibration solutions to be employed properly in the di
rect analysis of solid samples, suppresses unselective absorption, and
substantially shortens the time of analysis.
