摘　　要：采用氢氧化铁共沉淀,分离卤水中大量盐类,用盐酸溶解沉淀,在微酸性溶液中,直接以活性炭吸附卤水中微量金,然后对富集物进行光谱测定。该方法灵敏度高,测定结果可靠,可满足卤水中痕量金的批量检测。Coprecipitation with ferric hydroxide used to separate large quantities of salt brine,and precipitation was dissolved by hydrochloric acid.Trace gold of brine was directly adsorpted by activated carbon in slightly acidic solution,and then the product of enrichment was determinated by spectrometry.The method is sensitive,and measurement results are reliable to meet the mass production of trace gold in brine.
