highly effeicient removal of diazinon and malathione pesticides from fruit sample by using cu doped zeloitic imidazolate framework 8 (zif-8)

The zif-8 substrate was constructed using the solvothermal method with the central zinc metal, and the cu metal doping procedure was performed on the zif-8 substrate during the galvanic replacement process. the selected organophosphorous pesticides (opps), including diazinon and malathion, were extracted and determined in different types of real samples, including cherry, banana, and grape samples, and also agricultural water, using the adsorbent made during the process reinforced hollow fiber solid phase micro extraction combined with high performance liquid chromatography (hplc) [1]. pesticides, such as organochlorines, rodenticides, herbicides, fungicides, and fumigants, are used to prevent, eradicate, repel, or alleviate pests. opps, which from to the pesticide family, are the most widely used insecticides on the planet [2]. in this study, zif-8 was synthesized using a simple solvothermal approach, and the doping procedure was carried out using the galvanic replacement method. the resultant substance was then utilized as an adsorbent in the hf spme procedure to extract relevant analytes. select analytes were extracted using cu@zif-8 metal doping absorbent, desorbed to methanol, and analyzed using hplc uv in this methodology. in order to attain the maximum extraction efficiency, library studies and initial experiments are being used to assess the parameters affecting the extraction process. these parameters were already evaluated using the placket burnman experimental design, and then optimized using the box behnken design, with optimal points established for each of the parametersthe relative standard deviation (rsd) of the procedure for diazinon and malathion was reported to be (2.7% - 0.7%) under optimal circumstances. finally, based on the findings, it was demonstrated that the proposed approach has a high ability to extract and analyze selective analytes in a wide range of real samples [3].
