摘要
Using aqua regia as the medium,trace gold was separated from ores by a self-designed micro chromatographic column online separation and enrichment system, and measured by flame atomic absorption spectrometry. The condition of the gold and enrichment with the P<SUB>350 micro chromatographic column in the process of atomic absorption spectrometry absorbing and effusing solution were optimized. Compared with the method of existing off-line separation and enrichment, this method shows the advantages of higher efficiency, decreased time, and lower cost. The results for the practical sample test are satisfactory.
