Abstract

PURPOSE:To detect the presence or absence of manganese in a metallic material by using a water-containing material impregnated with mixed solutions of acidic solutions of nitric acid, ammonium persulfate and sulfuric acid and a phosphoric acid 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, whereby it is brought into contact with the metallic material 1. Mixed solutions of an acidic soln. consisting of silver nitrate, ammonium persulfate and sulfuric acid forming the red purple complex of the permanganic acid by reacting with manganese and a phosphoric acid soln. hiding iron by forming iron phosphate are used for the above-mentioned reagent. Prescribed current is flowed to the circuit for about 5sec, to allow manganese ions to elute from the metallic material 1 into the mixed solutions of the absorbent cotton 3, thence the content of manganse is detected from the intensity of the color formed by reaction with the silver nitrate-ammonium persulfate.
