| Abstract: | Interference of matrix modifiers and the atomization behavior of Pb with different test technique, determinating Pb in naphta with platform graphite furnace AAS have been studied. Mg(NO3)2 as a very good matrix modifier was described. The characteristic mass of Pb is very high, and the interference of matrix is very low. |
