Ion-transfer voltammetry at a polarized room-temperature molten salt/water interface.
Tetraoctylammonium cation forms a room-temperature molten salt (RTMS) with 2,4,6-trinitrophenolate anion. The RTMS is immiscible with water (W) and forms a stable RTMS/W interface. It has been shown that the RTMS/W interface can be electrochemically polarized. A well-defined voltammetric wave due to the transfer of thiocyanate ion across the RTMS/W interface was observed within the potential wi...
متن کاملIon transfer voltammetry by a simple two polarized interfaces setup.
Cyclic voltammetry and square wave voltammetry have been used to investigate the transfer of highly hydrophilic ions, including anions and cations, by a simple two polarized interfaces setup. The expression of apparent half-wave potential has been established detailedly by virtue of theory of sampled-current voltammetry involving semi-infinite linear diffusion, which indicates that the property...
متن کاملEvidence of tetraphenylporphyrin monoacids by ion-transfer voltammetry at polarized liquid|liquid interfaces.
We present a simple methodology to illustrate the existence of tetraphenylporphyrin monoacid based on ion-transfer voltammetry at a polarized water|1,2-dichloroethane interface and organic pK values are also estimated.
متن کاملVoltammetry of ion transfer across the electrochemically polarized micro liquid-liquid interface between water and a room-temperature ionic liquid, tetrahexylammonium bis(trifluoromethylsulfonyl)imide, using a glass capillary micropipette.
Ion transfer across the polarized interface between a room-temperature ionic liquid (RTIL) or room-temperature molten salt, tetrahexylammonium bis(trifluoromethylsulfonyl)imide (THAC(1)C(1)N), and water has been studied voltammetrically using a micro liquid-liquid interface formed at the orifice of a glass capillary micropipette. A small current of nanoampere level circumvents the problem of th...
متن کاملCyclic voltammetry at micropipet electrodes for the study of ion-transfer kinetics at liquid/liquid interfaces.
Cyclic voltammetry at micropipet electrodes is applied to the kinetic study of ion transfer at liquid/liquid interfaces. Simple and facilitated transfer of an ion that is initially present outside a tapered pipet was simulated by the finite element method, enabling complete analysis of the resulting transient cyclic voltammogram (CV) with a sigmoidal forward wave followed by a peak-shaped rever...
