Özet:

 


Chlordane is only one of the persistent pesticides used
in some countries despite the ban. Removal of chlordane, a severe threat to all living things, was
performed using nicotinamide-modified poly (2-hydroxyethyl
methacrylate-glycidyl methacrylate), poly(HEMA-GMA)-Nic, polymeric cryogels in this study. Pesticides are
practically insoluble in water. For that reason, ethanol is used as a solvent
which is not chemically dangerous and easily accessible in every laboratory. As
an adsorbent, poly (HEMA-GMA) polymeric cryogels
previously synthesized in the literature have been modified using nicotinamide.
The modification of poly(HEMA-GMA) with nicotinamide is the first in the literature. Removal of chlordane in alcohol
medium has been accomplished exploiting
the alcoho-phobic interaction, which was
the first indication in our previous study. Structural analysis of poly(HEMA-GMA)-Nic
was performed using Fourier transform infrared spectroscopy (FT-IR) and
elemental analysis methods. Scanning electron
microscopy (SEM) was used to understand
the surface morphology of cryogels. Surface area and cavity volume calculations
were determined by applying N2
adsorption method and swelling test. The interaction time and maximum
adsorption capacity were identified as 5
minutes and 64.61 mg chlordane/g cryogel
for 300 mg/L chlordane concentration and 108.818 mg chlordane/g cryogel for 800 mg/L chlordane concentration during
the adsorption experiments. Cyclohexane, toluene, chloroform, dichloromethane,
acetone, and acetonitrile were used as
solvent to observe the solvent effect on adsorption of chlordane onto the
polymeric material. As expected, the removal of chlordane was performed with the highest adsorption
performance in cyclohexane with the lowest dielectric constant.
