✦ Synopsis

Differential capacity of polycrystalline silver electrode in aqueous KF solutions containing thiourea (TU) of concentrations from 0.001 to 0.25 mol drnm3 has been measured by the previously described potentiostatic method CM. Brzostowska-Smolska et al., J. electroanal. Chem. 89, 389 (1978)]. The TU adsorption is discussed on the basis of differential capacity results and the potential shift caused by TU concentration changes. Furthermore, the surface pressure has been obtained by integration of the A ECN vs bM curves for a number of TU concentrations.
