Pang, Yue-Hong published the artcileCovalent organic framework modified carbon cloth for ratiometric electrochemical sensing of bisphenol A and S, HPLC of Formula: 80-09-1, the publication is Microchimica Acta (2022), 189(5), 189, database is CAplus and MEDLINE.
A novel ratiometric electrochem. sensor was developed based on a carbon cloth electrodeposited with silver nanoparticles and drop-coated by covalent organic framework (COF-LZU1) for simultaneous determination of bisphenol A (BPA) and bisphenol S (BPS). Carbon cloth exhibited a significantly larger electrochem. active area than common glassy carbon electrodes (27.5 times). Silver nanoparticles not only provided a stable reference signal but also enhanced electroactivity for the oxidation of BPA and BPS. COF-LZU1 with good adsorption performance and large periodic π-arrays promoted the enrichment of BPA and BPS to further increase the current response. Compared with the traditional single-signal electrochem. sensor, the developed ratiometric sensor exhibited better reproducibility and a wider linear range for BPA and BPS from 0.5 to 100μM with a limit of detection of 0.15μM. Furthermore, the developed sensor showed excellent stability and superior anti-interference ability. The real sample anal. for BPA and BPS has been successfully carried out in mineral water, electrolyte drink, tea, juice, and beer with recoveries of 88.3-111.7%. The developed ratiometric sensor is expected to be a candidate for the preparation of other electrochem. sensors and the anal. of addnl. practical samples.
