摘要：

A new method was developed for simultaneous spectrographic determination of 14 trace impurity elements in high purity gold after the reduction and separation of the matrix. The concentration of reductant, the hydrazine dihydrochloride, the acidity of the solution, the evaporation temperature and other required test conditions were determined. The detective inferior limits for these elements were in the range of 0.1 μg/g to 1 μg/g.
