Simple Ion Transfer at Liquid|Liquid Interfaces

Figure 2

Simulated voltammograms corresponding to the transfer of 𝐼^𝑧+ for different formal transfer potential values, Δ^𝑤_𝑜𝜙^𝑜′_𝐼𝑧+⋅Δ^𝑤_𝑜𝜙^𝑜′_𝐼𝑧+=−0.15 V (red line), 0.00 V (black line) and +0.15 V (blue line). Simulation parameters: 𝑧=1, 𝐴=0.18 cm², 𝜈=0.050 V s⁻¹, 𝐷^𝑊_𝐼+=1×10⁻⁵ cm² s⁻¹, 𝜉=𝐷⁰_𝐼𝑧+/𝐷^𝑊_𝐼𝑧+=1.12 (water|1,2-dichloroethane system) and 𝑐^initial_𝐼𝑧+=1×10⁻³ M.
