A series of carbon/attapulgite (C/APT) composites were fabricated by calcining chitosan/attapulgite (CTS/APT) composite and used as adsorbents for the efficient bleaching of palm oil. The effects of the dosage of CTS and calcination temperature on the structure characteristics of C/APT composites were investigated by FTIR, XRD,TGA, TEM and N2 adsorption–desorption isotherm techniques
