On the Tensammetric Waves of t-Amyl Alcohol(a)

Theory of tensammetry has been discussed on the basis of the kinetic theory of adsorp-tion at mercury-solution interface. (1) Tensammetric wave may be regarded as differential capacity vs. potential curve under a certain condition. Theoretical equations, relating the peak potential and the peak height to the bulk concentration, have been derived. (2) Adsorption phenomena and tensammetric wave of t-amyl alcohol have been ana-lyzed. Better agreement with the theoretical equation is obtained when the experimental results are analyzed for the positive and negative branches, separately. (3) The result are in harmony with the theoretical consideration. Parameters of ad-sorption equation have been calculated and discussed in view of Frumkin-Butler theory. Marked effect of anion on the tensammetric wave is understood by the present consideration.
