Using square wave anodic stripping voltammetry to overcome reproducibility issues with classical linear sweep anodic stripping voltammetry, Mn 2+ was quantified in non-aqueous solution with a limit of detection of 14 M. Square Wave Voltammetry (SWV) is a potentiostatic method that offers some advantages to common techniques like Cyclic Voltammetry (CV), in that the waveform is a series of pulses increasing along a linear baseline, where current is measured in a forward pulse and reverse pulse. The following is a brief introduction to the theory of SWV. Its use can be beneficial in analytical applications as well as in fundamental studies of electrode mechanisms. Peaks in the differential current vs. applied potential plot are indicative of redox processes, and the magnitudes of the peaks in this plot are proportional to the concentrations of the various redox active species according to: When viewed in isolation, the forward and reverse current waveforms mimic the appearance of a cyclic voltammogram (which corresponds to the anodic or cathodic halves, however, is dependent upon experimental conditions). Square-wave voltammetry is a technique that is readily available to anyone applying modern electrochemical measuring systems. Basic principle of voltammetry Voltammetry: A group of electrochemical methods based on measuring current (i)- applied potential curve during electrolysis - only a small amount of sample (analyte) is used Polarography: Invented by J . Because of the minimal contributions from non-faradaic currents, the use of a differential current plot instead of separate forward and reverse current plots, and significant time evolution between potential reversal and current sampling, high sensitivity screening can be obtained utilizing SWV.
