摘要：

The use of a combined palladium nitrate-magnesium nitrate chemical modifier allows a compromise higher pyrolysis temperature to be used for the simultaneous detection of arsenic, cadmium, lead, and selenium by graphite furnace atomic absorption spectrometry. For arsenic and selenium 900-degrees-C, for arsenic, selenium, and lead 600-degrees-C, and for arsenic, cadmium, lead, and selenium 350-degrees-C are recommended.
