Abstract

As organic pollutants are non-biodegradable, they pose a threat to the ecology and human health. Metol (MTL) is one of the most serious pollutants that gush into water sources. In this work demonstrates, a hydrothermal synthesized CuBi2O4 and ultrasonication approach for the construction of the Copper bismuth oxide/hexagonal boron nitride nanocomposite (CuBi2O4/hBN). Therefore, this consistent structure which enhance to strong interfacial interactions between the CuBi2O4 and hBN and also which facilitated the fast electron transfer efficiency in addition the physical and electrochemical characters of the CuBi2O4/hBN was characterize with supported by XRD, XPS, FE-SEM, HR-TEM, CV and DPV analysis. As a consequence, CuBi2O4/hBN/GCE surface modified electrode possessed a LOD of MTL 0.0052 µM at the sensitivity of 1.976 µA µM−1 cm−2 with 0.001 µM to 1987 µM linear rage. Furthermore, the feasibility of CuBi2O4/hBN/GCE to determine the MTL in the environmental water samples for instance pond, river, and tap water delivered a maximum recovery range about 97–99 % towards the detection of MTL. Therefore, CuBi2O4/hBN electrode material to attain superior electrochemical performances for the detection of MTL.
