摘要
样品经灼烧,采用王水、氢氟酸密封分解,用塑料泡沫分离富集,硫脲解脱,于波长242.8nm处,用原子吸收(GGX—600)测定金的吸光度。该方法应用于矿石分析生产中,结果与国家标准值相符。
The samples were burned, with aquaregia, hydrofluoric acid decomposition sealed with plastic foam separation and enrichment, thiourea relief. At the wavelength of 242.8nm, we use atomic absorption （GGX - 600） to measure the absorbance of gold. The method was applied to analyze the production of ore and the result was consistent with national standards.
