Molecularly Imprinted Polyvinylidene Fluoride Nanofibers for Selective Adsorption of Pesticides
With the increasing use of pesticides, concerns about their side effects have been raised for both environmental protection and human health. It is thus important to develop effective methods in their trace analysis and removal. Polyvinylidene fluoride (PVDF) is often used as membrane materials for pressure-driven water/waste-treatments with strong chemical resistance, high mechanical strength, and good processability. However, there are no specific interactions between PVDF and pesticides. In this study, fipronil was chosen as a template; molecular imprinting technique was used to construct tiny cavities with a specific shape in the PVDF membranes. These cavities will only interact with fipronil, thus leads to a high selectivity for analyte adsorption. Additionally, we have utilized an electrospinning process to fabricate a functional PVDF membrane with a large surface area. Furthermore, molecularly imprinted PVDF membrane with different template molecules will be prepared and studied. This type of membrane can have great potential for the detection and removal of specific pesticides and pollutants effectively and efficiently.
