USING GREEN NANO-PHYTOTECHNOLOGY FOR REMEDIATION OF WATER POLLUTED WITH FLONICAMID

Abstract

The preparation of eco-friendly low-cost activated charcoal (Ach),bentonite (Bent), nano zero-valent iron prepared from Marjoram (Mar-nZVI), nano zero-valent iron prepared from Moringa (Mor-nZVI), Mar-nZVI .Ach, Mar-nZVI . Bent, Mor-nZVI . Ach, and Mor-nZVI . Bent with and without Plantago major for the removal of flonicamid pesticide from aqueous solution has been investigated. Structure and morphology of Ach, Bent, Mar-nZVI, Mor-nZVI, Mar-nZVI.Ach, Mar-nZVI.Bent, Mor-nZVI.Ach and Mor-nZVI.Bent were characterized byUV spectroscopy , Fourier transform infrared spectroscopy (FTIR), High-resolution transmission electron microscopy (HRTEM), field emission scanning electron microscopy (SEM). The results showed that, Mar-nZVI .Ach, Mar-nZVI .Bent and Ach have faster flonicamid removal at all treatment periods. The percent removal of flonicamid in the water reached 31.81%- 99.42 by Mar-nZVI. Ach, 26.22%-100% by Mar-nZVI . Bent, 28.21%-100% by Ach compared with 1.68%-46.59% in water solution without nZVI or adsorbents between 2hours-8days. Flonicamidwas removed more quickly in the presence of Plantago major L. plus nZVI.Ach and Bent than that by P. major alone. The uptake of P. major roots and translocation of P. major leaves in the water polluted with flonicamid were lower efficient in accumulation of flonicamid from water under the treatments of P. major L. plus nZVI and plus nZVI .Ach and Bent than that by P. major alone. Conclusively, from these results it be concluded that plantago major L. plus FeNps .Ach and Bent plays a major role for the remediation of flonicamid-contaminated water.
