This Technical Specification specifies the determination of trace elements in aqua regia or nitric acid digest solutions of sludge, treated biowaste and soil, using atomic absorption spectrometry with electrothermal atomisation 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 0,1 mg/kg to 0,01 mg/kg, depending on the element to be determined.
