【摘要】:利用還原C法提取雞毛中可溶性角蛋白后產(chǎn)生的殘渣,通過簡單的物理方法處理后制得致密多孔的角蛋白海綿材料.針對增塑劑對角蛋白海綿結(jié)構的影響進行了實驗研究,結(jié)果發(fā)現(xiàn),甘油質(zhì)量分數(shù)4%時,其機械性能最佳,拉伸強度為5.04 MPa,斷裂伸長率為8.60%,完整性和柔韌性最好.利用紅外光譜儀對組成殘渣的分子基團等進行了表征,以有機揮發(fā)性氣體丙酮作為實驗對象,考察孔隙率和吸附溫度等因素對雞毛角蛋白海綿墊吸附性能的影響.實驗結(jié)果顯示:當角蛋白海綿墊的孔隙率為82.59%、環(huán)境溫度為25℃時,對丙酮揮發(fā)性氣體24 h的吸附量為205.4 mg/g;吸附1個月后達到飽和狀態(tài),飽和吸附量達374.8 mg/g.充分利用廢棄雞毛這一資源,對于去除環(huán)境中氣體污染物具有一定的應用潛力.
[Abstract]:The residue of soluble keratin from chicken hair was extracted by reductive C method, and the dense porous keratin sponge material was prepared by simple physical treatment. The effect of plasticizer on the structure of keratin sponge was studied in this paper. The results showed that the mechanical properties were the best when glycerol content was 4%, the tensile strength was 5.04 MPa, and elongation at break was 8.60%. Integrity and flexibility are best. The molecular groups of the residue were characterized by infrared spectroscopy. The effects of porosity and adsorption temperature on the adsorption performance of chicken hair keratin sponge pad were investigated by using acetone as the experimental object. The experimental results show that when the porosity of keratin sponge pad is 82.59% and the ambient temperature is 25 鈩,
