ABSTRACT
MgAl-LDH was directly impregnated with biochar to fabricate MgAl-Biochar (MgAl/BC) and applied to remove methyl orange (MO) and methyl red (MR). The XRD, BET, FTIR, TG-DTA and SEM analyses were conducted to characterize the prepared material. The result of XRD characterization diffraction peaks at 2θ 11.47, 22.86, 34.69, and 61.6 shows that the precursor was successfully transformed to MgAl-BC. The FT-IR analysis at vibration 1010, 1381,3447 and 1635 cm-1 illustrated that the composite was well formed. The BET analysis showed that the surface area of the MgAl-BC composite was 111.404 m2/g which was larger than that of the precursor, equal to 23.15 m2/g. The kinetic model of the adsorption study both MR and MO were fitted to PSO and followed the Langmuir model with adsorption capacities for MR 142.857 mg/g and MO 128.205 mg/g. The regeneration study of composite indicated higher efficiency than the pristine and show good stability of adsorption process in five cycles.
