The avain feather is natural polymer material resources. It includes large quantity of keratin, among of which proteins take up 83%. The feathers modified by methyl methacrylate at Ammonium Persulfate(APS)-Sodium Bisulfite(SBS) as initiator are applied to treat chrome tanning waste water. The factors such as dosage, pH of chrome tanning waste water, adsorption time were discussed. The adsorption conditions are optimized, which is modified feather 1.5g, chrome tanning waste water 22 mL, pH4.5, and static state adsorbed 20h.
