Abstract
Notice of Retraction

The wool was treated as Cr(III) adsorbent. The influence of the ratio of wool and solution on the rate of removal Cr(III) from wastewater and the adsorption isotherm of Cr(III) by wool were studied. The result shows that the adsorption isotherm of Cr(III) by wool was typical L model. The model of Langmuir is better than Frenudlich to describe the change regularity of the equilibrium adsorption amount with concentration Cr(III). As the temperature is 293K, 303K, 313K, the coefficient linear regression of Langmuir reached 0.982, 0.997, 0.999 and the saturated adsorption capacity is 15.87 mg/g, 19.61 mg/g, 20.83mg/g. The adsorption kinetics indicated that the process of wool adsorption divided in rapid surface adsorption and slow internal pervasion. The data of the relationship of adsorption time and adsorption capacity were simulated by the pseudo-first and a second order model, the latter is better. The structure of wool, treated wool and absorptive wool were characterized by FTIR. The amido, carboxyl and sulfhydryl, etc. act as important groups in wool adsorption process.
