Breyer school has given the name of tensammetric peak to this type of wave and pointed out that the tensammetric peak height obeys the Langmuir adsorption isotherm, shown by eqn.(1), where<BR><I>a</I>=amount of adsorbed substance per unit area of electrode surface, <BR><I>Z</I>=the maximum number of adsorption sites per unit area, <BR>ω=adsorption coefficient, <BR><I>C</I>=concentration of surfactant in the bulk of solution.<BR>If the tensammetric peak height <I>i<SUB>p</SUB></I> is proportional to the amount of adsorbed substance <I>a</I>, as Breyer states, then the reciprocal of peak height plotted against the reciprocal of concentration should give a straight line, as eqn. (2) shows.<BR>On the other hand, upon investigating the concentration dependence of the tensammetric peak potential, Senda and Tachi report that <I>i<SUB>p</SUB></I> plotted against log <I>C</I> shows a roughly linear relationship.<BR>Employing the nine species of surface-active substance, as tabulated in Table I, the concentration dependence of the tensammetric peak height is measured. The concentration range is so chosen that the peak height dose not exceed 500 MΩ<SUP>-1</SUP>; otherwise the effect of circuit resistance is not negligible. In general, a surfactant shows two peaks, namely, the peak at a potential more positive than the electrocapillary maximum potential <I>i<SUB>p</SUB></I><SUP>+</SUP> and the peak at a more negative potential <I>i<SUB>p</SUB></I><SUP>-</SUP>. In the present investigation, the peak height of <I>i<SUB>p</SUB></I><SUP>+</SUP> is measured with exception of benzyl alcohol with which both <I>i<SUB>p</SUB></I><SUP>+</SUP> and <I>i<SUB>p</SUB></I><SUP>-</SUP> are measured.<BR>The method of linear regression is applied to the 1/<I>i<SUB>p</SUB></I> <I>vs</I>. 1/<I>C</I> and the <I>i<SUB>p</SUB></I> <I>vs</I>. log <I>C</I> plots, and the corresponding two correlation coefficients <I>r</I><SUB>1</SUB> and <I>r</I><SUB>2</SUB> are evaluated. The difference between <I>r</I><SUB>1</SUB> and <I>r</I><SUB>2</SUB> is tested according to the method given in the review of Doerffel by means of eqn. (3). As shown in Figs. 2, 3, 4 and 5, and also in Table I, the linear relationship between 1/<I>i<SUB>p</SUB></I> and 1/<I>C</I> holds, in general, much better than that between <I>i<SUB>p</SUB></I> and log <I>C</I> does.<BR>In the plot of 1/<I>i<SUB>p</SUB></I> <I>vs</I>. 1/<I>C</I>, however, with several surface-active substances, the straight line crosses the ordinate at a negative value of 1/<I>i<SUB>p</SUB></I>, as illustrated in Figs. 2 and 4. If 1/<I>C</I> tends to zero, 1/<I>i<SUB>p</SUB></I> should show a positive value on the basis of Langmuir adsorption isotherm.
