Add to ORKGAfter calcium nitrate (used as the spectroscopic buffer) and cadmium nitrate (used as the internal standard) were added to the sample solution, the mixed solution was evaporated and a part of the nitrate salt deposited was excited in the cavity of graphite electrode by direct current are method with a medium quartz spectrograph. By this salt powder method, at least 3γ of arsenic, 1γ of antimony, 0.3γ of tin and lead, and 0.1γ of bismuth could be determined spectrographically
