本文引用了大量国内外文献,就我国应用最广的各种金的分离富集技术与发射光谱测定方法、金样及其分析结果的处理方法、结合作者个人经验作了讨论。实践表明:当前,影响微金分析误差的主要因素,已不是光谱定量测定方法,而是金样均匀性及由制样而引起的加工误差。到目前为止,活性炭吸附与泡塑吸附仍然是最适于发射光谱定量测定的两项分离富集技术。
In this paper, a large number of domestic and foreign literatures are cited, and the methods for the separation and enrichment of various gold and the methods for determining the emission spectra of gold, the gold samples and their analytical results are widely used in China, and the author’s personal experiences are discussed. Practice shows that, at present, the main factor affecting the error of the micro-gold analysis is not the method of quantitative spectrometry, but the uniformity of the gold sample and the processing error caused by the sample preparation. So far, activated carbon adsorption and foam adsorption are still the two most suitable separation and enrichment techniques for emission spectrometry.
