Copper has a catalytic action on the reduction of ferric ion in an acidic solution with sodium thiosulfate. Effects of various metals and concentrations of acids on this reaction were studied. By measuring the time required until the dark violet of ferric thiosulfate complex in the presence of potassium thiocyanate was decolorized under a constant condition, the determination of microamount of copper, as small as 0.001〜0.1 per cent, in various metals was carried out.
