| 摘 要： | 通过模拟实验获得附载金、锑的泡塑样品，并对其进行了硫脲解脱法、灰化法、硝酸加氧化剂消解法的比较实验，确定采用硫脲解脱法是地电化学(泡塑)样品金、锑的最佳解脱方法，通过正交实验及其结果分析确定了最佳实验条件。利用硫脲解脱一原子吸收光谱法对某隐伏金锑矿床82件地电化学(泡塑)样品进行了测试，分析结果显示出有明显的金、锑异常，指示了重要的勘探靶区。

| Abstract: | A foam enrichment method for gold and antimony in the same geoelectrical chemical samples was reported in this paper. The foam samples were obtained through simulating experiments. Three methods for gold desorption (sulfourea desorption method, ashing method and digestion by HNO_(3)+oxioxigant) were compared and the results showed that the sulfourea desorption method was the best one. The gold-desorption conditions were optimized through the orthogonal test. Combined with atomic absorption spectrometry (AAS), Au and Sb in 82 geoelectrical chemical samples were analyzed with satisfactory results. |
