Description
Various types of pesticides are used to improve agricultural productivity and maintain the freshness of agricultural products. However, due to increasing and uncontrolled application, pesticides and their derivatives represent a major threat to entire ecosystems. Therefore, development of new methods for their detection and monitoring is of primary matter. In present work, the unmodified boron-doped diamond (BDD) electrode was utilized for quick, simple, efficient, and sensitive electrochemical detection of mesotrione (MST), a hazardous herbicide used primarily in maize culture. This is the first efficient application of BDD electrode for MST detection. MST undergoes an oxidation process, on the surface of the BDD electrode, at a high potential value of +1.4 V. The detection limit of 75 µM and remarkable selectivity among the common interfering molecules were achieved. Furthermore, a straightforward practical application of the method in real samples (corn-origin food products) analysis was demonstrated.
