abstract = {The goal of this work was to develop polymer-based
heterocycle for water purification from toxic pesticides
such as difenoconazole. The polymer chosen for this purpose
was cellulose nanocrystalline (CNC); two cellulose based
heterocycles were prepared by crosslinking with 2,6-pyridine
dicarbonyl dichloride (Cell-X), and derivatizing with
2-furan carbonyl chloride (Cell-D). The synthesized
cellulose-based heterocycles were characterized by SEM,
proton NMR, TGA and FT-IR spectroscopy. To optimize
adsorption conditions, the effect of various variable such
as time, adsorbent dose, pH, temperature, and difenoconazole
initial concentration were evaluated. Results showed that,
the maximum difenoconazole removal percentage was about
$94.7\%,$ and $96.6\%$ for Cell-X and Cell-D, respectively.
Kinetic and thermodynamic studies on the adsorption process
showed that the adsorption of difenoconazole by the two
polymers is a pseudo-second order and follows the Langmuir
isotherm model. The obtained values of ∆G ° and ∆H
suggest that the adsorption process is spontaneous at room
temperature. The results showed that Cell-X could be a
promising adsorbent on a commercial scale for
difenoconazole. The several adsorption sites present in
Cell-X in addition to the semi crown ether structure
explains the high efficiency it has for difenoconazole, and
could be used for other toxic pesticides. Monte Carlo (MC)
and Molecular Dynamic (MD) simulation were performed on a
model of Cell-X and difenoconazole, and the results showed
strong interaction},
