Doping cork fibers with nanomaterials for the removal of organo-phosphorous pesticide

AbstractOrgano-phosphorous pesticide removal was evaluated using cork fibers. In this study, three cork fibers were doped with nanomaterials (graphene, TiO2 and ZnO) and used as filtration. To obtain an optimized condition different pH and temperatures were tested. Diazinon, chlorpyrifos and carbaryl are three pesticides which were removed by treating cork composite in pH 4, 7 and 10. The results show that acidic pH has better effect on removing pesticide. On the other hand, The time from 0 to 600 min was tested for each sample to gain best time for the removal. By achieving the optimized condition (pH and time), the effect of temperature was investigated, and the results show that at 30 °C the maximum removal of pesticide was achieved. Samples were analyzed by field emission scanning electron microscopy, EDX and elemental mapping, and finally, the results conclude that due to porosity of cork and nanomaterial properties, this method has excellent effect on the removal of pesticide.Keywords: Cork fiberspesticidenanographenenano-TiO2nano-ZnO AcknowledgmentsThe authors do not express their gratitude to anyone.Ethical approvalDisclosure statementAll authors declare that they have no conflicts of interest.Data availability statementData are available on request from the authors.The authors confirm that all the research meets ethical guidelines and adhere to the legal requirements of the study country.
