| dc.description.abstract | Simple ion transfer across the immiscible water/o-nitrotoluene, water/benzonitrile and water/o-dlchlorobenzene interfaces has been studied using ac and dc cyclic vol\ammetry. The standard Gibbs energies of transfer from water to the organic solvents for several ions have been determ ined. The results are compared with theoretical values calculated using the model of ionic solvation. The transfer across the imm iscible water / nitrobenzene interface of transition metal (Fe, Co, Ni, Cu and Zn) - terpyridine complexes has been studied using ac and dc cyclic voltammetry, linear sweep voltammetry and absorption spectroscopy. From the voltammetric measurements and convolution integral analysis , thermodynamic and transport properties have been evaluated. The transfer behaviour of cuprous ion across the water/l ,2-dlchloroethane interface facilitated by 2,2' -biquinoline has been studied and the mechanisms for the transfer process are proposed. The structure of the electrical double layer at the water /o-nitrotoluene and water/a-dichlorobenzene interfaces containing different base electrolytes with different concentrations has been studied by impedance measurements. The capacitance values obtained from experiments have been compared with the values calculated from the Gouy- Chapman theory. AnalysiS of the results has Indicated the absence of speCific adsorption at the water /0- nltrotoluene in terf ace. | en_US |
