| Abstract: | Determination of Ir in Pt-Ir alloys by the oxidation-reduction titration was studied.The influences of the oxidation conditions,the consumption of Cl 2-bearing water,the rate of flow and time for inletting air,and the coexisting elements,such as Pd,Rh and Ru were discussed.An analytical method was developed,to determine the synthetic samples and Pt-Ir alloys.The standard deviation of 0.044% can be achieved when the content of Ir is 25.0%. |
