Paper Title:
Study on the Absorption of Wool for Cr (III) from Water
  Abstract

The adsorbability of the wool with three different treatment ways were studied in this paper. The effects of different factors including pH from 2.0 to 4.5, time from 4h to 24h, temperature from 20°C to 40°C, concentration of Cr(III)from 0.343 g/L to 2.185g/L were investigated by single factor and static experiment. The adsorption of Cr(III)includes chemical and physical processes, the wool of WAW mainly depends on physical adsorption, the wool of SKW and the wool of SWW are mainly suported by chemical adsorption. The results showed that each step of treatment to wool can increases its adsorption capacity obviously and the maximum absorption capacity of swelling wool, degreased wool, washed wool reached 13.4 mg/g, 9.76 mg/g, 4.22 mg/g respectively under pH4.5, 30°C, the concentration of Cr(III) 2.185g/L conditions absorb 12h. The wool will be a promissing biomass adsorbtion meatrials.
