The application of anodic stripping voltammetry for the quantitative analysis of Cd, Pb, and Cu in natural waters is described in this experiment. 

Describe clearly the principle and operation of potentiometric stripping analysis (PSA). How it is differed from anodic stripping voltammetry (ASV) What is the quantitative signal What is its advantage over ASV ... 

Radiochemical yields are 80-95% for zinc and quantitative for cadmium. The average relative standard deviation was 25% for zinc and better than 10% for cadmium. The detection limit of the method is 50 ppm cadmium in the ash. Analysis of two Illinois coals with unusually high cadmium content (17 and 21 ppm) gave results in good agreement with those obtained by atomic absorption and by anodic stripping voltammetry (4). The recent development and testing of a radiochemical method for the determination of zinc, cadmium, and arsenic in coal and fly ash, by Orvini et al. (14), has already been discussed in the section on arsenic. 

Waggon and Jehle [121,122] have reported on the quantitative detection of triphenyl and tri-, di-, and monobutyltin species in aqueous solution by a combination of liquid-liquid extraction, thin layer chromatography and anodic stripping voltammetry. 

Summary of Method. The sample is digested with fuming HN03 in an enclosed Teflon chamber. After removal of the carbonaceous matter in a muffle furnace, the residue is dissolved in HC1, which is then neutralized with anhydrous ammonia. The resultant salt is dried, dissolved in a measured quantity of water, and subjected to analysis by anodic stripping voltammetry. Quantitation is achieved by the method of standard additions.

In anodic stripping voltammetry, however, it is a requirement that the deposited metal be completely removed from the electrode surface. As we found subsequently, it is possible to achieve quantitative stripping when the solution concentration is small. As... 

Stripping Voltammetry One of the most important quantitative voltammetric techniques is stripping voltammetry, which is composed of three related techniques anodic, cathodic, and adsorptive stripping voltammetry. Since anodic strip-... 

Abrasive stripping voltammetry — Technique where traces of solid particles are abrasively transferred onto the surface of an -> electrode, followed by an electrochemical dissolution (anodic or cathodic dissolution) that is recorded as a current-voltage curve [i]. It allows qualitative and quantitative analysis of metals, alloys, minerals, etc. The technique is a variant of - voltammetry of immobilized particles [ii].
