1) Reaction between 1-phenylthiosemicarbazide and various metallic ions was examined and it was found that the compound gave sharp coloration with copper, silver, gold, zinc, cadmium, mercury, bismuth, iron, cobalt, nickel, and platinum ions.
2) It was found that the color reaction with cupric ion was especially sharp and that the isoamyl alcohol solution of this reagent was able to detect 2×10-8g./cc. of cupric ion.
3) Reagent test papers were prepared and the limit of the detection of copper ion and the limit ratio, in the presence of other metallic ions, were examined with these papers.
4) The use of this reagent as the color developer in the paper chromatography enabled the concurrent separatory detection of various metallic ions.
