TL;DR: In this paper, a trace analysis using square wave voltammetry at the dme is presented, which is shown to have the same order of sensitivity as differential pulse polarography but is much faster to perform.
Abstract: : 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.

Journal ArticleDOI
TL;DR: It has been shown that DNA modified with osmium (DNA-Os) accumulates at the hanging mercury-drop electrode during a waiting time in a wide range of potentials and will produce at neutral pH a well-developed reduction peak at about -1.2 V due to scanning in the cathodic direction.

Journal ArticleDOI
TL;DR: In this paper, the electrochemical behavior of cadmium and lead metal ions was investigated in the presence of different pH buffers [3-(N-morpholino)-2-hydroxypropanesulfonic acid (MOPSO), 2-(Nmorpholine)ethane sulfonic acid, MES, and 3-(n-morpholine), by various methods [differential pulse anodic stripping voltammetry (DPASV), differential pulse polarography (DPP) and cyclic voltage amortization (CV)].

Journal ArticleDOI
TL;DR: Anodic stripping voltammetry and differential pulse polarography are used to study complex formation between Cu(II), Pb(II, Zn(II) or Cd(II)) under concentration conditions which approximate those in natural waters as mentioned in this paper.
