| Abstract: | 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. |
