Abstract
The method describes the determination of phosphorus in copper artifac ts by graphite furnace AAS using La(NO3)(3) as the matrix modifier. Th e sensitivity of the procedure is calculated as 3500 pg (pico grams). The accuracy of the method was assessed by analyzing two MBH copper al loys. The results obtained are in good agreement with the certified va lues. Phosphorus, up to 0.006% in 25-mg samples taken from six copper coins, was successfully determined.
