Effect of ligand protonation on the facilitated ion transfer reactions across oil|water interfaces. V. Applications of forced hydrodynamic conditions

Facilitated proton transfer across liquid | liquid interfaces under forced hydrodynamic conditions. Determination of partition coefficients of neutral weak bases

“…Those analyses were centred mainly on the effect of water autoprotolysis on the transfer processes of the protonated species [34]. The model was corroborated by experimental results obtained from the transfer of quinine across the H 2 O|1,2-dichloroethane interface, and the corresponding transfer mechanism was analysed in terms of the current-potential and theoretical concentration profiles [24,28,33]. In recent papers, we developed the models for the facilitated proton transfer or charged species transfer across liquid|liquid interfaces including ion pairing [31,32] and non-ideal electrolyte solutions [32] to calculate the halfwave potential for neutral weak bases [31] and weak acids [32].…”

“…The theoretical approximation for the processes of facilitated transfer of protons or the transfer of protonated species has aroused great interest in the area [12,16]. Dassie and co-workers [24,28,[33][34][35] have developed the general equations for a model of ion transfer reactions across the oil|water interface assisted by a neutral weak base. Those analyses were centred mainly on the effect of water autoprotolysis on the transfer processes of the protonated species [34].…”

Facilitated Ion Transfer Reactions Across Liquid|Liquid Interfaces Assisted by a Neutral Weak Acid: A Theoretical Approach

“…A theoretical approach for modelling the facilitated proton transfer or protonatable species transfer across L j L interfaces was developed by several authors. [9,14,[23][24][25][26][27][28][29][30][15][16][17][18][19][20][21][22] On the other hand, physical-chemical properties of the ligand (partition constant, charge, acid-base activity, etc.) as well as its chelating capacity for a given cation (complex formation constants in both phases, and stoichiometry of the formed complexes) determine the nature of the charge transfer process across the L j L interface.…”

“…A theoretical approach for modelling the facilitated proton transfer or protonatable species transfer across L|L interfaces was developed by several authors [9,14,23–30,15–22] . On the other hand, physical‐chemical properties of the ligand (partition constant, charge, acid‐base activity, etc.)…”

An integrated theoretical-experimental approach to understand facilitated proton transfer-electron transfer coupled reactions at thick-film modified electrodes

“…These processes have been widely studied in both buffered and unbuffered aqueous solutions. In particular, our research group has been focused on understanding the physicochemical processes that control the proton facilitated transfer via water autoprotolysis [17,21,[27][28][29]. In the case of buffered aqueous solutions, we have examined the variation of the peak current values vs. pH or volume ratio to determine partition coefficients of neutral weak bases at the oil|water interface.…”
