Utilization of nanostructures with high binding capacity to remove pesticide pollutions from water

Use of pesticides to control crop destroying insect has increased exhibited in last two to three decades. Pesticides and their residues were entered in soil, air and may be leached into ground and surface waters due to their widespread usage. Therefore, removal of pesticides from environmental medium is very important. Hence, poly (HEMA-MAT) nanostructures, novel affinity chromatography matrix for adsorption of deltamethrin synthesized and the optimum conditions for the adsorption of deltamethrin from water samples were also determined in this study. Poly (HEMA-MAT) nanostructures were characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and elemental analysis. Maximum adsorption capacity was found to be 315.6 mg/g and the adsorbed amounts per unit mass of nanostructures reached to a plateau value at about 800 mg/L. It was observed that adsorption was more favour in acidic medium. Amounts of deltamethrin in real water samples such as river and ground waters were determined and removed efficiently using poly (HEMA-MAT) nanostructures. Also, we concluded that the poly (HEMA-MAT) nanostructures can be effectively used in deltamethrin adsorption without detectable losses in their initial adsorption capacities.
