摘要
地球化学探矿要求对大批量样品的多元素进行快速而准确的测定。等离子体直读光谱法由于其一系列的特点而对此较为适应。在分析方案的制定中,为了全面地满足高效、准确、大批量的要求,本法选择了酸溶样,以一套合成的标准溶液,在一个折衷条件下,于一份样液中测定尽可能多的各种浓度级下的主要、次要以及痕量元素。
Geochemical exploration requires a large number of samples to be analyzed rapidly, precisely and accurately for a lot of elements. This task has been fulfilled by ICP-AES well. Samples were decomposed with hydrofluoric acid and perchloric acid and analyzed on a 60-channel Jarrell-Ash 1160 Plasma Atom-Comp. Analytical results determined on 37 elements in 8 Chinese Geochemical Standard Samples are presented and agree well with usable values. Several international Geochemical Reference Samples have been analyzed and correlation data are also presented.
