项目摘要

Adsorption of low-molecular-weight organic compounds to silk fibroin, silk sericin and wool keratin was investigated ; the adsorption of dyes in water (1), vapor of organic compounds in air (2), amino acids in water (3) and organic compounds in water (4) were examined. Following results were obtained.l) "Adsorption of dyes in water" Five kinds of acid dyes to keratin or fibroin fiber and their powder was observed. The dyes adsorbed more at higher temperature to wool fiber. On the other hand, no temperature effect was observed in the adsorption to silk fibroin. When regenerated powder keratin was used, the adsorption of dyes did not depend on temperature. Thus, the roll of cuticle in wool fiber was important.2) "Adsorption of vapor of organic compounds in air "Each protein showed similar adsorption property to each other but the amount of adsorbed compounds was different. Specific adsorption property was seen for each of synthetic polypeptides.3) "Adsorption of amino acids in water "Fibroin fiber and powder adsorbed lysine predominantly from the mixture of amino acids. On the other hand, poly (glycine), poly (L-alanine) and poly (L-valine) etc. gave the adsorption of acid amino acids such as glutamic acid and aspartic acid.4) "Adsorption of organic compounds in water " It was seen that contamination of organic compounds such as chloroform in water could be removed by the adsorption with fibroin fiber.

研究了低分子有机物在丝素、丝胶和羊毛角蛋白上的吸附，考察了染料在水中的吸附(1)、有机化合物在空气中的蒸气(2)、氨基酸在水中的吸附(3)和有机物在水中的吸附(4)。研究结果如下：1)五种酸性染料对角蛋白或丝素纤维及其粉末的吸附作用。温度越高，染料对羊毛纤维的吸附越强。温度对丝素蛋白的吸附无明显影响。当使用再生粉末角蛋白时，染料的吸附不依赖于温度。因此，羊毛纤维中角质层的卷曲是非常重要的。2)有机化合物在空气中的吸附。每种蛋白质都表现出相似的吸附性能，但被吸附的化合物的量不同。3)“水中氨基酸的吸附”丝素纤维和粉末主要从氨基酸混合物中吸附赖氨酸。另一方面，聚(甘氨酸)、聚(L-丙氨酸)、聚(L-缬氨酸)等对谷氨酸、天冬氨酸等酸性氨基酸有吸附作用。4)水中有机物的吸附实验表明，用丝素纤维吸附可以去除水中氯仿等有机物的污染。
