摘要

The current work, we have demonstrate an electrochemical determination of 4-nitrotoluene (4-NT)based on zinc cobaltate nanoflakes (ZnCo 2 O 4 ; ZnC Nfs) The ZnC Nfs was synthesized by simple Co-precipitation method and its physicochemical properties were systematically studied with variousanalytical and spectroscopic techniques such as XRD, FESEM and EDX. Moreover, the proposed ZnCNfs modified with Screen-printed carbon electrode (SPCE) after that directly used for theelectrochemical determination (4-NT). The ZnC/SPCE shows an excellent electrochemical activity forthe (4-NT) detection. The as prepared ZnC Nfs provide a highly selective and sensitive electrocatalystfor the (4-NT) determination with good linear range response 0.05μM- 385.5μM and low detectionlimit 0.044μM. The ZnC/SPCE electrochemical sensor established the outstanding selectivity, wellstability and reproducibility.
