A new potentiometric titration method coupled with multivariate calibration using a flow injection technique for the simultaneous determination of multi-components in alloy has been developed. the titrant is a mixture of EDTA and sodium fluoride, both mercury film electrode and fluorinion selective electrode are inserted in the flow cell. In a process of titration, both the potentiometric of mercury ion and the mixed proportion of reactants at each titration point can be obtained simultaneously from the two electrodes, and then the concentration of each component in the mixture can be obtained from the titration curves by multivariate calibration method. The method is free of volumetric and time measurements, and reduces the consumption of reagents and samples. The method is also very quick in analysis rapidity. The method has been applied for the simultaneous determination of copper, lead and zinc in alloy samples with the relative standard deviation of 0.18%~0.45% and the recovery of 99.5%~101.6%.
