Linear voltammetry can be developed with manual potentiostats, where the potential sweep is made in a staircase form using a potentiometer. In manual potentiostats the voltage scan rate is not controlled, and the behavior of this parameter and its influence on the voltammetric response have not been widely reported. In this work, a study of the potential sweeps and its influence on the diffusion current in the manual staircase voltammetry was done employing a minimal instrumentation micropotenti...
