摘要：

Ruthenium shows promise for use as a chemical modifier for the determination of ultratrace quantities of lead in solution when compared with the popular and widely used palladium. There is experimental evidence that ruthenium reacts with lead in the graphite tube to form the intermetallic compound PbRu2. The amount of ruthenium had a dramatic effect on the absorbance profile for the lead signal. (C) 1997 Academic Press.
