Valorization of keratin biofibers for removing heavy metals from aqueous solutions [PDF]
, 2018 Four common waste keratin biofibers (human hair, dog hair, chicken feathers, and degreased wool) have been used as biosorbents for the removal of heavy metal ions from aqueous solutions. Different parameters of the biosorption processes were optimized in
