Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Voltammetric methods for estrone determination were developed using a cathodically pretreated BDD electrode with DPV or SWV. Analytical curves were obtained for estrone concentrations from 0.20 or 0.10 to 2.0 µmol L⁻¹, for DPV or SWV, with detection limits of 0.20 and 0.10 µmol L⁻¹, respectively. The SWV method was successfully applied in estrone recovery studies in different water matrices. Additionally, these recovery results were reasonably similar to those attained using HPLC/UV‐vis. Comparatively to other electroanalytical methods based on different carbon electrodes, the here‐reported novel methods yield very good results, being adequate for estrone determination in environmental samples.</p> </abstract>
