On the design of an A.C. Polarograph

Catalytic and Kinetic Waves in Polarography

“…On the basis of the effect of different factors on the potentials of tensiometric wa ves the dependence of the adsorption of the compounds, causing the tensiometric waves, can be determined. By this method effects of supporting electrolytes on the tensiometric curves of ethyl, n-amyl, and cyclohexyl alcohols were investigated [313]. The deficiencies of Breyer's tensiometric waves were mentioned in the previous chapter (see page 53).…”

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

“…•¬ (18) The first and second terms in the r.h.s. of this equation represent the reverse S-shape (positive branch) or S-shape (negative branch) variation of the capacity, whereas the third term is responsible for the characteristic peak of the tensammetric wave .…”

“…Equations (18) to (21), though very approximate ones , would be used as a basis of analyzing the tensammetric wave under approriate conditions . It is noted that the features of the present results are highly dependent upon our assumption on the adsorption equation and a Vs. E curve, particularly on the dependence of the adsorption energy , cb(E), on the electrode potential.…”

Ninety Years of Polarography

“…When on the d.c. potential applied to the dropping electrode an alternating voltage of small amplitude was superimposed and the resulting alternating current was measured as a function of direct potential, in the thus introduced “a.c. polarography”[23] instead of polarographic waves appeared maxima of alternating current in place of half‐wave potentials, and the curves became sensitive to adsorption occurring at the electrode surface. (When applied specifically to study adsorption phenomena the a.c. polarography was called “tensammetry”.…”
