“…In most experiments, the classical voltammetric stripping protocol has been utilized, but also mentioned were procedures where the stripping was done by differential pulse voltammetry (DPV) [21], by square wave voltammetry (SWV) [69], by chronoamperometry [69], and by chronopotentiometry [40].…”

Stripping analysis is a two-step procedure. In the first step, the analyte is accumulated at an electrode surface either by electrolysis or by adsorption. In the second step, the deposited material is removed, typically by electrolysis. The second step is the source of the analytical signal. Sensitivity of the method mainly depends on the amount of substance which is transferred to the electrode surface during accumulation. The methods reviewed make use of unconventional techniques to enhance efficiency of accumulation. By ultrasound, a combined action of thermal and mechanical impacts, partially with extreme energetic states, causes improvement of analytical results. Heating of electrodes or of a nearelectrode area induces laminar electrolyte flow acting as stirring, combined with increased surface temperature that is helpful to lower kinetic hindrances. Magnetic fields in a cell with arbitrarily increased deposition current enhances convection without additional thermal effects. Most of the techniques reviewed are able to improve the efficiency of stripping analysis much more than could be done by driving classical stirring up to the limits.

“…16 metals, including lead 28 and manganese 42 (where the BDD substrate leads to significantly greater sensitivity than can be achieved using glassy carbon) 49 in complicated matrices, without the need for mercury or solution degassing. With this particular analytical problem in mind, sono-CSV offers the immediate benefit over ASV in that lead analysis is completely unaffected by the presence of copper ions in solution, even in great excess.…”

The complicated analytical challenge of lead determination in the presence of high levels of copper, has been investigated using anodic and cathodic stripping voltammetry, on a variety of mercury free electrode substrates. CSV was found to be ideally suited towards lead determination in a predominantly copper matrix, due to the lack of interference from copper ions on the anodic electrochemistry of lead. A CSV technique, incorporating the use of power-ultrasound and a borondoped diamond electrode is presented. The sono-CSV technique has been optimised to give a lower limit of detection of aqueous Pb 2+ ions of 1.6×10 -9 M for a 300 s PbO2 deposition, requires no solution degassing, is mercury-free and totally free from copper-intermetallic interference. As an extreme example, the technique was applied successfully to the determination of lead content of a copper-lead alloy, after a simple acid digestion protocol. Excellent correlation was observed between the known lead level and experimental results, with the technique being sensitive towards the detection of 3.3×10 -4 % (w/w) lead in copper, for the analysis of a 10 mg sample.

“…Electrochemical methods for manganese detection have been reported previously. 2,3,6,[12][13][14][18][19][20][21][22][23][24][25][26] For instance, Rusinek and colleagues 2 developed a new sensor based on polymercoated indium tin oxide for manganese detection in natural water samples. Kang et al 3 utilized a copper-based electrochemical sensor with a palladium electrode to determine manganese in water samples.…”
