Ternary MnFeZn layered double hydroxides as an efficient material for the electrochemical sensing of flutamide

Abstract

Layered double hydroxides (LDHs) have been gaining interest in electrochemical sensors due to their ease of making and significant performances. In this work, we have developed a simple and low-cost method for the preparation of ternary LDH. The MnFeZn-LDH was prepared and initially characterized to explore its formation. Further, the glassy carbon electrode (GCE) modified with MnFeZn-LDH was employed for the electrochemical analysis of flutamide (FLA). Thus, the prepared ternary MnFeZn-LDH was prominent with better sensitivity of about 5.04 μAμM−1 cm−2 and selective over several interferants injected over the MnFeZn-LDH fabricated electrode. The limit of detection was appreciable with a linear range of 0.019–2735.79 µM about 12.9 nM. Also, other technical analyses showed good electrochemical performances as a higher rate of repeatability and reproducibility. The stability of the electrode was retained for 50 cycles and the real sample detection in river water showed significant potentiality. Thus, the as-described work evolves the better enhancement with MnFeZn-LDH towards FLA detection. The better electrocatalytic properties of the prepared LDH paves the way for its exploration in various application.
