Abstract

Pesticides are one of the most dangerous compounds found in fruits, vegetables, and other food products, which is why they are considered a serious threat. Therefore, accurate and correct measurement of chemical pesticides is necessary to ensure the ecosystem's health [1]. Therefore, a suitable method should be developed to determine the concentration of various kinds of pesticides such as imidacloprid, propiconazole, and tebuconazole in real samples. Here, a new sorbent based on the combination of POMs and UiO-66-NH2@GO has been synthesized, and finally, the synthesized sorbent is placed on the surface of the polymeric membrane. The prepared sorbent has been used for the solid phase extraction of the selected analytes. The extracted analytes were eluted by an appropriate eluent and analyzed by HPLC-UV. The obtained results showed that the sorbent is suitable for extracting pesticides. Optimization of extraction factors was done using a univariate optimization method. In optimal conditions, the limits of detection (LODs) were calculated from 0.30 -1. The obtained RSDs% were also lower than 5. This method was successfully used to determine some pesticides in different agricultural products.
