Here, we report the facile route for the synthesis of graphene oxide-functionalized manganese dioxide (GO-MnO₂@Tau (GMT) and GO-MnO₂@CA) (GMC) nanohybrids and their use as adsorbents for removal of selected dyes from industrial effluents.
these nanohybrids were also tested for antibacterial activity in wastewater.
manganese dioxide nanoparticles were synthesized by redox reaction between potassium permanganate (KMnO4) and manganese acetate (Mn(CH3COO)2.4H₂O) and functionalized with taurine (H3N* CH₂CH₂SO3) and caproic acid (CH3(CH₂) COOH) to produce MnO₂@Tau and MnO2@CA.
these functionalized-MnO2 were then exploited as reinforcement in graphene oxide (GO) to fabricate nanohybrids.
the nanohybrids were characterized for their morphology, structure, crystallinity and thermal behavior by scanning electron microscopy (SEM), X-ray diffraction (XRD), fourier transform infra-red (FTIR) spectroscopy, UV-Visible spectroscopy and thermogravimetric analysis (TGA).
the results were reproducible with negligible variation in physical properties among different batches.
they were investigated for adsorptive removal of methylene blue and malachite green and effect of temperature and quantity of adsorbent were studied.
the adsorption of both dyes followed pseudo second order kinetics.
the addition of MnO₂@tau and MnO₂@CA as nanofillers within GO has led to decrease in its crystallinity.
this may be attributed to the dispersion of MnO₂@tau and MnO₂@CA within layers of GO which causes breakage of regular stacks of GO.
the antibacterial activity of GO-MnO2@Tau and GO-MnO2@CA nanohybrids were tested against two bacterial strains (Gram-negative E.
coli, and the Gram-positive S.
aureus) and the results revealed efficient inhibition of these pathogens.
