Abstract
Metol (MTL) is a highly significant organic compound that plays a crucial role in numerous applications as a monochromatic material. It has an impact on humans, plants, and animals and it raises serious environmental concerns. The present scenario necessitates the development a rapid, cost-effective, precise, and specific method for detecting metol in environmental and biological samples. In this study, the electrochemical sensor was developed using a modified electrode based on the Au@Ce2Sn2O7/MXene nanocomposite. The nanocomposite was thoroughly examined through phase composition analysis, elemental analysis, and morphological studies. The modified electrode exhibits exceptional selectivity, cyclic stability, storage stability, and reproducibility. The proposed sensor shows a wide linearity range (0.00125 to 1021.96 μM), low detection limit (5.63 nM), and high sensitivity (0.403 μA·μM–1·cm–2). The suggested sensor's consistency was confirmed by real-time monitoring of MTL in several environmental and biological samples with a high percentage of recovery.
