本研究以家禽业废弃物鸽子羽毛为原料，通过冷冻干燥法制备了多孔性角蛋白海绵，并首次将其应用于油脂吸附剂。提出了一种以廉价的亚硫酸钠为还原剂溶解羽毛角蛋白的改进方法，使所有反应试剂的浓度大大降低。再生后的角蛋白海绵对液体石蜡和大豆油的吸附量均在30 g/g以上，且具有良好的持油能力，表明该角蛋白海绵具有作为油脂吸附剂的潜力。
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.
