Experimental verification of earlier theoretical work for square wave voltammetry at the dropping mercury electrode is given. Experiments using ferric oxalate and cadmium II in HC1 confirm excellent agreement with theory. Experimental peak heights and peak widths are found to be within 2 of calculated results. An example of trace analysis using square wave voltammetry at the dme is presented. The technique is shown to have the same order of sensitivity as differential pulse polarography but is much faster to perform. A detection limit for cadmium in 0.1 M HC1 for the system used here was 7 x 10 to the minus 8th power M.
