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 by UV
spectroscopy , Fourier transform infrared spectroscopy (FTIR), Highresolution
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. Flonicamid was 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.
