- Abstract
- In this thesis, quaternary ammonium polybromide (QBr2n+1) droplets and heptyl viologen bromide dual redox ionic complexes were electrochemically studied through stochastic chronoamperometric analyses. The first part contains the comparison of ion partition coefficients at an interface between water and electrochemically generated quaternary ammonium polybromide (QBr2n+1) droplets (water│QBr2n+1) in QBr aqueous solutions containing different acids (HAs). The concentration of Br− in QBr2n+1, CBr-(QBr2n+1) is linearly proportional to CA-(aq) with the proportionality constant, which was estimated from the difference between the two partition coefficients of H+ and A− from water toward QBr2n+1, KH+-KA-, and the ratio of the mean activity coefficient of the aqueous over that of the QBr2n+1 phase, γ±,aq/γ±,QBr2n+1. CBr-(QBr2n+1) also shows the linear function of CQ+(aq) with (γ±,aq/γ±,QBr2n+1)KQ+ as its proportionality constant. The stochastic chronoamperometric analyses of QBr2n+1 droplets during their particle-impacts on Pt UME in acidic solutions containing either N-methyl-N-ethyl pyrrolidinium bromide (MEPBr) or ethylpyridinium bromide (EPyBr) as model QBrs can provide indirect information about CBr-(QBr2n+1). Based on the experimental data, the relative order to be KC+(Li+ or Na+), KH+, and KA-: KC+(Li+ or Na+)
