Rapid electrographic determination of gold in gold-copper alloys and silver in silver solders was worked out. The method consisted of stripping of alloy constituents into Toyo filter paper moistened with a supporting electrolyte solution and then of measuring the intensity of color developed with colorimetric reagent spectrophotometrically. Suggested electrolyte solution were 0.5 M NH4Cl for gold alloys and 0.01 M KNO3 for silver solders. After electrographic stripping (4 V, 10 mA, 10 sec) of alloy constituents into the filter paper coupled with pressure 2 kg pet 6.25 cm2, the filter paper was treated with 0.5M hydroxylamine sulphate for gold and with 1% potassium chromate for silver to develop the colored pattern to be measured at 600 mμ and 480 mμ, respectively. The method seems to be of special value for rapid and practically nondestructive determination of gold and of silver in their alloys.
