A preparation method for the treatment of Cr(VI)composite adsorbent Ca-AC
The effects of weight ratio of Eucalyptus and CaCl2,carbonization temperature and carbonization time on the composite adsorbent(Ca-AC)were studied.The best conditions for composite adsorbent(Ca-AC)were obtained: the weight ratio of CaCl2 to the eucalyptus sawdust was 2:1; the carbonization temperature was 650 °C; the carbonization time was 80 min.The Ca-AC yield reached 28.88%; the Cr(VI)adsorption value was 131.03 mg·g-1.The morphology and structure of the adsorbents were characterized.The results showed that the specific surface area of Ca-AC can reach 713 m2·g-1.The carboxyl,hydroxyl,lactones groups and amino could be determined on the activated carbon surface.
