| 摘 要： | 由于ICP采用加电弧装置,使等离子体性能有所改善,提高了样品的蒸发效率,一定程度上抑制了基体效应和粒度效应,对样品中Cu、Zn、Fe、Mg、Pb、Co、Ba等元素的测定,取得较好的效果。

| Abstract: | A method for the simultaneous determination of Ba, Co, Cu, Fe, Pb, and Zn in flee flour, wheat flour and tea leaves with a powder introduction ICP arc system has been developed. With a single set of synthetic standards using starch as the matrix, the several dements in samples can be determined with good accuracy under optimized conditions, provided the standards and samples are mixed with graphite powder (2 : 3). Depending on clcments, the RSDs are ranging from 5 to 14%. |
