On the Adsorption of Octanoic Acid at the Mercury/Electrolyte and Air/Water Interfaces

The Adsorption and Condensed Film Formation of Cetyltrimethylammonium Bromide at the Mercury/Electrolyte Interface

“…All these reagents were obtained from Merck, were of high purity (pro analysis or suprapur), and were used as received. It has already been mentioned in (22) that the heating of suprapur KCl to 600…”

Effect of the Supporting Electrolyte on the Adsorption of Octanoic Acid at the Mercury/Electrolyte Interface

“…The repeated cyclic procedures consisting of compressing, sucking off, and expanding the adsorption layer of the octanoic acid solution resulted in a "surface chemically pure solution." Surface tension and capacitance measurements revealed the purity of this solution (25,27).…”

“…All these reagents, obtained from Merck, were of a high degree of purity (suprapure or proanalysi) and were used as received. It was mentioned in (25) that the heating of suprapure KCl to 600…”

“…A Hewlett-Packard Model 419A LF was used for these measurements. The details of the measuring apparatus were published (25). A hanging mercury drop electrode was used as the working electrode.…”

“…The values of the area per molecule for the mercury/water interface obtained indicated a rather dense packing of the molecules at high octanoic acid concentrations. In (25) we investigated the adsorption kinetics of octanoic acid at the mercury/electrolyte interface by means of the capacity-time transients at a potential in the region of maximum adsorption. For low concentrations of octanoic acid and for the short-term region, the transients were theoretically described with a diffusion-controlled adsorption process according to the Delahay-Tranchtemberg law.…”
