Trace gold is concentrated with foam plastics, which with the existence of ferric trichloride. by extrication of thiocarbamide(1.2%), using the technology of slope heating and Zeeman graphite tube. After the process of drying, pyrolysis, atomize,cleaning, the trace gold which included in geochemical samples would be assayed. By making calibration with the stock which disposed as same as the samples and assayed national standard materials, the detection range of measurement is wide, the limit of the method is 0.2×10-9, gold recovery is wel , analytic rate is fast, this method is appropriate for assaying trace gold which included in geochemical samples.
