Electrosorption of neutral organic compounds from solvents of high dielectric constant. Triphenylphosphine oxide as a probe molecule

Mechanism of amalgam formation electrode reactions in nonaqueous solvents. Combined analysis of interfacial distance parameters and steric factors

“…the electrode characteristics, the reactant and inhibitor concentrations, the measuring parameters etc, between the dc and ac measurements. For this reason, although most of the above systems have already been reported in previous papers [20][21][22][23], the entire set of experimental data of the present work is based on new measurements.…”

“…Cd(CH 3 COO) 2 (Ventron, GMBH) and Zn(CH 3 COO) 2 (Aldrich, 99.99%) were dried at 120°C for 24 h before use. PC (Merck, for synthesis) and F (Fluka, puriss pa) were purified as in [20,21].…”

“…The reference electrode used was an AgjAgClj0.1 M aq LiCl electrode connected to the dme compartment where AN is the acetonitrile, the reference solvent, WS is working solvent, reported in [21], allow for the conversion of the electrode potential scale of the present work to the solvent independent potential scale of bis(biphenyl)chromium (I)/(0) [24]. Among the chemicals used, LiClO 4 (Ventron, GMBH), TPO (Merck, for synthesis), TPBi (Fluka purum), TPSb (Fluka, purum), MeOH(Fluka, puriss pa) and AN(Merck, pro analysi) were used as received.…”

“…For the needs of the s.f. analysis the following values of the projection areas of the adsorbed particles on the electrode surface were taken from [20,21],…”

Differential capacitance and electrochemical impedance study of surfactant adsorption on polycrystalline Ni electrode

“…Due to their inhibitory action, organophosphorus compounds may be proved to act as effective corrosion inhibitors. Among them, triphenylphosphine oxide and triphenylarsine oxide were frequently used as reaction inhibitors [11] and also as probes of Hg/solution [12,13] and Ag/ solution interface [14], while other alkyl substituted phosphinoxides [11], phosphines, arsines [15], and phosphonium salts [16,17] have received less attention.…”
