Abstract
PURPOSE:To detect the presence or absence of copper in a metallic material by using a water-containing material impregnated with mixed solutions of a weak alkaline soln. consisting of cuprizon and ammonia as well as ammonium acetate and sodium flouride solution. 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, wherey it is brought into contact with the metallic material 1. Mixed solutions of a weak alkaline soln. consisting of cuprizon and aqueous ammonia forming the blue complex of copper cuprizon by reacting with copper, an ammonium acetate soln. acting as a buffer and a sodium flouride hiding iron by forming iron fluoride are used for the above- metnioned reagent. Prescribed current is flowed to the circit for about 5sec, to allow copper ions to elute from the metallic material 1 into the mixed solutions of the absorbent cotton 3, thence the content of copper is detected from the intensity of the color formed by cuprizon reaction.
