“…The LOD values obtained for estrone determination using different carbon electrodes and electrochemical techniques are presented in Table 2. From these data, it can be inferred that the performance attained with the CPT BDD is comparatively very good (in the case of the work by Wang and Jseng 29, the LOD value is significantly off the lower limit of the linear range). The LOD values attained simply using the CPT BDD electrode (for both SWV and DPV) are equal or close, respectively, to that reported by Muna et al.…”

“…28 determined equine estrogens, including estrone, by RP‐HPLC using electrochemical detection with a carbon fiber electrode; a limit of detection ( LOD ) of 15 µmol L −1 was attained. Wang and Jseng 29 also used a HPLC system with electrochemical detection by a dual thin‐layer GC electrode for the quantitative measurement of five estrogens in human and rabbit urine; despite the range of linearity being 0.18–3.7 µmol L −1 , an astonishingly low LOD value was reported: 1.1 nmol L −1 .

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.

HPLC−EC Analysis of Estrogenic Compounds: A Comparison of Diamond and Tetrahedral Amorphous Carbon Electrode Performance

et al. 2018

High pressure liquid chromatography (HPLC) with amperometric detection was used to quantify estrogenic compounds in water samples. The main goal was to compare the detection figures of merit for boron‐doped diamond thin‐film (BDD) and nitrogen‐incorporated tetrahedral amorphous carbon (ta‐C : N) thin‐film electrodes. The target analytes were estrone, estradiol, and estriol. The BDD and ta‐C : N electrodes were investigated because of their excellent properties, which include a wide potential window, low background current, microstructural stability at high potentials, low limits of detection, weak molecular adsorption, fouling resistance and response reproducibility. ta‐C : N electrodes have not yet been investigated extensively in electroanalysis and are receiving increasing interest because they exhibit many of the excellent electrochemical properties of BDD electrodes and they can be deposited at room temperature by physical vapor deposition. The results reveal as low or lower background current and noise for the ta‐C : N electrode, as compared to the BDD electrode, and comparable or superior analytical detection figures of merit for all three emerging pollutants. The linear dynamic range for both electrodes was from 0.2 to 100 μmol L−1 for estriol, and 0.4 to 100 μmol L−1 for estradiol and estrone, and the sensitivity ranged from 9.1 to 11.2 mA mol L−1. For all three analytes, the limit of detection (S/N=3) ranged from 0.16–0.35 μmol L−1 (45‐95 ppb) for BDD and 0.20–0.34 μmol L−1 (58‐95 ppb) for ta‐C : N.
