A method for the determination of traces of copper by its catalytic action on the reaction between phosphomolybdic acid and sodium thiosulfate has been proposed. The reaction rate is proportional to the concentration of copper in the range of 0.08-0.70 γ/ml. The relative deviation for a single determination is withia ±10%. A deviation of 1.5℃ for room temperatures in preparing the standard curves and in determination of copper in solutions may be tolerated without introducing noticeable error. 25 ml of the copper solution to be analyzed contains 4.0ml of 10-2M H2SO4, 2.0ml of 1% phosphomolybdic acid and 1.0 ml of 0.1 M Na2S2O3 solution.Na, K, NH4, Ca, Mg, Zu, Mn, Co, Ni, Cd up to lmg/25ml, Cl, NO3 up to 2×10-3M, WO4, H3BO3 up to 4 × 10-4M and Al, Cr, Bi up to 100 γ/25 ml do not interfere. While Fe, Fe, F, PO4, AsO4 and VO3, interfere with the determination of copper.The presence of vanadate promotes the catalytic action of copper. When the concentration of copper lies between 0.02-0.26 γ/ml, the reaction rate is proportional to the square of the concentration of copper.
