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 P
## Abstract The metal content (Cu, Fe, Ni, Pb) of Finnish margarines manufactured in 1978โ80 were investigated by the flameless atomic absorption spectrophotometry method. Copper, iron and nickel were digested by the dry ashing method whereas for lead both dry ashing and wet ashing were employed. T
