- Abstract:
- The adsorption properties of Cr( V) on hydrothermal treated rice husks were investigated and theadsorption capacities of rice husks with series treatment time were compared.The results showed that the ricehusk with 4 hours treatment exhibited the best adsorption capacity,being four times that of raw rice husk.Thermogravimetric analysis and Fourier transform infrared spectroscopy of the series rice husks demonstratedthat the active hydroxy group on rice husk dehydrated and condensed after the hydrothermal treatment. Theeffects of pH, contact time,initial concentration and temperature on the adsorption capacity were investigated,showing that the adsorption capacity increased with pH decreasing,temperature increasing，initial concentra-tion increasing and contact time increasing,and the Freundlich adsorption isothermal model was well fitted.
