摘要
在KBr存在下,用小体积醋酸丁酯萃取金后,用无火焰原子吸收法测定化探样品中痕量金的分析方法较化学富集光谱法具灵敏度高(检出下限可达0.05×10^(-9)、精度好、简便快速、成本低等优点。通过批量化探样的检验,证明该方法足已满足化探样品对金的测定要求。
Compared with the spectrum method of chemical accumulation, the analyse method of trace gold determination of geochemical samples by non-flame atom absorption after extracting gold with small volume of butyl acetate in case that there is KBr in the sample is characterized by a high sensitivity (determination limit can be as low as 0. 05 × 10-9), high precision, prompt operation and low cost. The method is proved to be suitable for the gold determination of geochemical sample through patch geochemical sample testing.
