Abstract

Polyaniline-lignin composite were prepared by polymerization of aniline in the presence of lignin using (NH4)2S2O8 as oxidant. Properties of the obtained polyaniline-lignin composite were studied by FT-IR spectra, thermal gravimetric analysis (TGA) and scanning electron microscopy (SEM). Results on absorption of Cr(III) by polyaniline-lignin composite showed the optimal absorption conditions of Cr(III) were pH of solution 5,0 and contact time of one hour. Absorption of Cr(III) followed the Langmuir model as evidenced by a good coefficient of correlation value (R2 = 0.9986). The maximum adsorption capacity, qmax from the Langmuir model was found to be 71.43 mg/g for Cr(III) and are higher than the separate polyaniline or lignin.
