Graphitization of flax shive cellulose modified by citric acid: properties of magnetic composites and their dye adsorption capability: Fullerenes, Nanotubes and Carbon Nanostructures: Vol 30, No 10


Summary

Magnetic composites had been synthesized in an inert medium inside the temperature vary T = 500–1000 °C by one-stage pyrolysis of microcrystalline flax shive cellulose modified by citric acid (MCCA) and homogeneously impregnated with Fe(NO3)3. Catalytic graphitization was studied by the thermogravimetric evaluation technique. The crystal construction, pore growth, morphological construction and floor chemistry of carbon composites had been characterised by the N2 adsorption-desorption, XRD, SEM and FTIR strategies. The onset temperature of MCCA graphitization was discovered to be equal to 600 °C. The magnetic carbon supplies had been examined as adsorbents for elimination of anionic methyl orange (MO) and cationic methylene blue (MB) dyes. The very best equilibrium adsorption capability in MB and MO was discovered within the magnetic composites synthesized at 700 and 800 °C.
