On the adsorption and condensed film formation of binary mixtures of dodecyl-, tetradecyl-, hexadecyl-, and octadecyl-trimethylammonium bromides at the mercury–electrolyte interface

On the adsorption of cetyldimethylbenzylammonium chloride at the mercury/electrolyte solution interface

“…In [27][28][29] we studied the adsorption and condensed film formation of dodecyltrimethylammonium bromide (DTAB), tetradecyltrimethylammonium bromide (TTAB), hexadecyltrimethylammonium bromide (CTAB), and octadecyltrimethylammonium bromide (OTAB) on the hanging mercury electrode in the temperature range 5-45 • C. The results showed a marked effect of the chain length of the alkyl chain on film formation. A condensed film was formed at extreme negative potentials and at room temperature only for CTAB in the presence of KBr, with a very low capacitance value, approximately 1.5 µF/cm 2 .…”

“…A combination of this kind of curves can give information on the surface micellization. The effect of the temperature on adsorption is also studied, ranging from 1 to 50 • C. The aim of the paper is to compare its adsorption with the other alkyltrimethylammonium salts studied in [27][28][29] and mainly with hexadecyltrimethylammonium bromine, which has a similar chain length, and to study the influence of the anions.…”

Effect of the deaeration on the adsorption of some cationic surfactants at the mercury/electrolyte solution interface

“…There are some differences in the adsorption of the three surfactants studied at the mercury/solution interface and the condensed film is formed at different potentials and under different conditions [20][21][22][23]. The organic molecules forming the film displace ions and solvent molecules in building up the film [28].…”

“…The adsorption and condensed film formation of hexadecyl-(CTAB), and octadecyl-(OTAB) trimethylammonium bromides on the hanging mercury electrode was studied in KBr as supporting electrolyte and at various temperatures [20][21][22]. A condensed film was formed at negative potentials and at room temperature only in the presence of CTAB.…”
