Description / Abstract:
This Technical Specification specifies the determination of
trace elements in aqua regia or nitric acid digests or other
extraction procedures of sludge, treated biowaste and soil, using
atomic absorption spectrometry with electrothermal atomization in a
graphite furnace. The method is applicable for the determination of
the following elements:
Arsenic (As), cadmium (Cd), cobalt (Co), lead (Pb), antimony
(Sb), thallium (Tl), vanadium (V).
This method may be applied to other elements. The lower working
range is approximately 0,01 mg/kg to 0,001 mg/kg, depending on the
element to be determined.
