Square wave voltammetry of surface-active, electroinactive compounds

Square wave voltammetry (SWV) is generally considered as being insensitive to capacitive currents, which is true if it is compared to alternating current voltammetry, but less so if the comparison is made to pulse and differential pulse voltammetry. In fact, the sensitivity of SWV to capacitive current depends on the frequency of signal. In this communication a basic theory of square wave voltammetry of surface-active, electroinactive compounds is developed. It is shown that in tensametry SWV appears as useful alternative to phase selective ac polarography.
