Abstract

PURPOSE:To analyze molybdenum in metal material simply and with high reliability by using a specific reagent and performing measurement by the electrograph method. CONSTITUTION:Mixed solution composed of acid solution containing thiocyanate and sulfuric acid and of L-ascorbic acid solution and having a composition shown in the table is used as the reagent. That is, the anode end 5 of an electrode 2 is connected with metal material 1 to be inspected, and then absorbent cotton 3 impregnated with the aforesaid reagent solution is picked up with electroconductive tweezers serving as a cathode end 4 and is made to contact with the material 1, and electrification is made for about 5sec. Next, coloration (red-brown) caused by reactions between molybdenum and thiocyanate is measured and thereby molybdenum in the metal material 1 is analyzed (for judgement of the presence, half quantification).
