| Abstract: | A novel kinetic spectrophotometric method for determining the amount of copper is proposed based upon the catalytic effect of it on thephosphomolybdic acid----iodide redox reaction, and the optimal conditionsare established. The calibration graph is linear for 0~0.64ug/ml Cu2+, and the detection limit is Ing/ml. The method is used to determine the amount of copper in La2O3, the recoery rate is 95.6%,and RSD=2.2%. |
