摘要：
The results of this study of sawdust-polyaniline nanocomposite synthesized by a chemical method for Cr(VI) treatment in the environment are presented. Cr(VI) adsorption on a composite was determined by colorimetry. The results showed that sawdust-polyaniline composite synthesized with an aniline : sawdust ratio equal to 0.5 had an adsorption degree of 21.4 mg g-1 and adsorbed nearly 99% of the Cr(VI) after 2 h. The composite could be used for the adsorption of Cr(VI) from waste water. The Cr(VI) adsorption ability of the composite slightly depends on the pH value of the medium. The adsorption is fast during the first half hour and then the rate decreases. © 2010 Vietnam Academy of Science & Technology.
