Hello Aravind Sp . No, it's not the same. In linear sweep voltammetry, a linearly varying potential is imposed on the cell, but in linear stripping, a fixed pre-concentration potential is imposed during a time and then linearly swept. The aim of the preconcentration potential in stripping is to improve the detection limit of the method. I attach some images. Regards.
It is important to note that the preconcentration step (at a fixed potential) may be of different nature. It may be electrolytic preconcentration, for instance, cathodic deposition of a metal followed by anodic stripping as in the case of anodic stripping votammetry, ASV, or adsorption preconcentration as in adsorptive stripping voltammetry, AdSV, where a surface active substance is accumulated on the electrode surface due to an adsorption process.
