Webmetals are measured in a second (stripping) step. This is achieved by the action of an oxidant present in the sample solution14. Derivative potentiometric stripping analysis (dPSA), a variant of potentiometric stripping analysis (PSA), is util-ised to facilitate evaluation of the analytical signal by us-ing its derivative. WebPotentiometric stripping analysis is a sensitive analytical technique. Before the SCP measurement starts a deposition stage at the deposition potential E dep is required. After this stage, the potential versus time is recorded. In this stage, the potentiostat is switched off and the measurement starts. Stripping chronopotentiometry (SCP).

Web2 Nov 2024 · Potentiometric stripping analysis (PSA) and its derivative modes (dPSA) are used for the determination of metal ions in traces. [1-13] They consist of two steps. In the first one, the electrode is kept at constant potential and metals are accumulated as amalgams. Then the amalgam is stripped by a chemical oxidant under open circuit …
WebThe method, which is based on potentiometric stripping analysis, is accurate, reproducible and requires little or no sample pre-treatment. Tin causes positive interference in the stripping signal. This interference effect can be reversed for up to 50 mg dm –3 of tin by the addition of 1 mg dm –3 of copper.
