Meaning of STRIPPING ANALYSIS in English

"A group of electroanalytical techniques for the determination of trace amounts of substances, consisting of two steps: preconcentration and analysis. The preconcentration involves the electrodeposition or adsorption of the substance to be determined on the surface of an electrode. This is followed by the ""stripping"" analysis of the substance by an electroanalytical technique. For example, traces of metal ions can be preconcentrated by cathodic electrodeposition followed by anodic dissolution (stripping). Or traces of halides (e.g., chloride) can be anodically preconcentrated at a mercury electrode as mercury salts, followed by cathodic stripping. "
