The main aim of this study is to synthesize porous carbon adsorbent from chemical precursor in order to prevent metal impurities that are commonly associated with porous carbon adsorbents derived from agricultural residues. Deferrated kaolinite was used as a template material for the synthesis of porous carbon adsorbent from polyfurfuryl alcohol (PFA). The structural and adsorption characteristics of the adsorbent were investigated using Fourier transform infrared (FT-IR) spectroscopy and methylene blue adsorption. FT-IR spectra showed that calcination of the kaolinite impregnated with polyfurfuryl alcohol, at 500℃ ensured carbonization of the polymer (between kaolinite layers) but did not collapse the mineral layer structure which is required for the creation of pores in the templated carbon. Results from the adsorption studies showed that for all the different initial concentrations of the methylene blue, the templated carbon had higher adsorptive capacity than non templated carbon from carbonized free polyfurfuryl alcohol.
