In this work, pigeon feathers, a kind of totally waste by-product from the poultry industry, were utilized to fabricate a highly porous keratin sponge in a very simple way by freeze-drying treatment of the dissolved keratin solution, and applied for the first time as an oil adsorbent. An improved method was proposed to dissolve the feather keratin using the inexpensive sodium disulfite as the reducing reagent for sulfitolysis reaction, with a much lower concentration of all involving reaction regents. Moreover, the regenerated keratin sponges obtained a high oil adsorption capacity of above 30 g/g for both liquid paraffin and soybean oil, as well as a good oil holding ability, suggesting that this keratin sponge might be a potential for use as oil adsorbent.
