Atomic absorption control of ultimate
allowable concentration of elements in meat products without sample dissolution
Abstract
To control maximum levels of As, Cr, Pb, Cd
and Sn in meat products, it was proposed to transfer them to a suspension of
140 mg/ml and use an atomic absorption spectrometer with a graphite furnace,
equipped with a probe attachment for a two-stage atomization of the suspension.
The working linear range covers 0,2–9 ultimate allowable concentrations. The
error is 2–3 times less than that of the methods with sample dissolution, and
it saves at least 12 hours of time.
Key words: meat, meat products, atomic
absorption analysis, two-stage probe atomization, graphite furnace, suspension.
