Článek Otevřený přístup peer-reviewedpublished The lead film electrode prepared with use of the combination of ex-situ and in-situ methods in stripping analysis of folic aci(Univerzita Pardubice, 2012) Tyszczuk-Rotko, KatarzynaIn this article, elaboration of a "hybrid" lead film electrode is reported. The strategy to create such an electrode is based on the combination of ex-situ and in-situ plating methods and also the use of a reversibly deposited metal mediator (Cd) for the lead film formation. Various plating conditions, which influenced the response of the “hybrid” lead film electrode to folic acid, were thoroughly optimized and discussed. The results have indicated that the sensitivity of the “hybrid” lead film electrode prepared with use of the metal mediator was remarkably improved compared to the in-situ and ex-situ plated lead film electrodes, and the “hybrid” lead film electrode prepared without use of the metal mediator could be applied to the determination of folic acid in tablets (preparative Folovit®) with satisfactory results.
