| Abstract: | Summary Surface activity of closely related organic compounds are compared by utilising the optimum concentrations corresponding to more negative peaks and concentrations required to remove or to suppress less negative reduction peak due to organic compound and due to metal ion to maximum extent instead of tensammetric peak by a. c. polarography. Surface activity measurements are pH dependent. The correlation between optimum concentrations of surface-active substance and the amounts of reducible species would be of great significance in suppressing the polarographic maxima in d. c. polarography.
