| 摘 要： | 氯化钠、溴化钾、碘化钾在石墨炉原子吸收光谱法测定铁、铜、铅、铋时产生强的背景。提高灰化温度和时间能消除或降低此干扰。铅和铋的测定能用铂或钯作基体改进剂,但是铂的效果更好。

| Abstract: | NaCl, KBr and KI were found to produce strong background in the determination of Fe,Cu,Pb and Bi in graphite furnace atomic absorption spectrometry. Increasing the charring temperature and time the interference could be removed or reduced. In the determination of Pb and Bi the platinum or palladium could be used as the matrix modifier,but platinum gave a better efficiency. |
