Abstract
PURPOSE:To detect the presence or absence of cobalt in a metallic material by using a water-containing material impregnated with mixed solutions of a nitroso R salt soln., a sodium acetate soln. and an ammonium fluoride and sodium citrate soln. CONSTITUTION:The anode end 5 of a power source 2 is abutted electricity-conductably on a metallic material 1, and absorbent cotton 3 which is a water-containing material impregnated with a coloring reagent is pinched with a pincette or the like of a good electric conductor which is a cathode 4, whereby it is brought into contact with the metallic material 1. Mixed solutions of a nitroso R soln. forming the orange complex of cobalt-nitroso R salt by reacting with cobalt and a sodium acetate soln. for controlling pH and an ammonium fluoride soln. hiding iron by forming iron fluoride and iron citrate are used for the above-mentioned reagent. Prescribed current is flowed to the circuit for about 5sec, to allow coablt ions to elute from the metallic material 1 into the mixed solutions of the absorbent cotton 3, thence the content of cobalt is detected from the intensity of the color formed by reaction with the nitroso R salt.
