Theory and Verify of Mensurate Cl- Ion by Flow Injection-Cathodic Potentiometric Stripping Analysis

In this paper, the theoretical equation of flow injection-cathodic potentiometric stripping analysis for Cl- ion determination was derived from theoretical analysis, and the experimental equation was summarized using multiple linear regression method. The result shows that the theoretical equation of flow injection-cathodic potentiometric stripping analysis for Cl- ion is: (dt/dE)max =K Ap r-1/2D2/3-1/6Vf1/2teCx-/is; that the experimental equation of multiple linear regression method is: (dt/dE)max Cl-1.86×1010Vf0.568 teC Cl-/is. The two results are similar on Vf-average flow rate, te-concentrate time, C Cl- -Cl- ion concentration and is constant current.
