Fig. 2. Response isotherms of B15C5SAM determined from the shift in C′ in response to increasing concentrations of Na+ (red squares) and K+ (blue circles) in H2O with 100 mM TEACl as supporting electrolyte, under static conditions. Isotherms were fitted to a Langmuir model (see ESI Section S1.6 for further details, and eqn (S1)†). Errors represent one standard deviation of three independent repeats.
