| dc.description.abstract | Potentiometric stripping analysis (PSA ) was applied to the interface between two immiscible electrolyte solutions ( ITIES ). The analysis was done on anions of thiocyanate, perchlorate and nitrate. Polyvinylchloride-nitrobenzene (PVC-nb) gel was prepared following the procedure introduced by Senda et al jBunseki Kagaku, 33 (.1984) E 371] and the PVC-nb gel electrode was constructed using polytetrafluoroethylene (PTFE) tubing as a main cell body. The behaviour of the cell was characterized by ac and dc cyclic voltammetry and reproducible voltammograms were obtained showing that the ion transport processes in both phases is diffusion controlled. The reversibility of the system was also tested using current reversal techniques. The dependence of transition time (T ) on deposition time and deposition Cor enrichment ) potentials was quali- tatively studied. From this preliminary study the method (PSA ) was found to be quite applicable for the electrolysis of ions across the ITIES, | en_US |
