摘要: 对双醛纤维素吸附明胶的各种条件、吸附产物的红外吸收和热重热解曲线图进行了研究。结果显示,双醛纤维素吸附的最佳pH值为8、最适温度为 40℃,其吸附量随时间、氧化度增长,4h 即达平衡,氧化度高于 100% 时吸附量基本稳定;吸附产物具有Schiff碱的红外特征吸收峰,热分解起始温度随吸附量提高。

Abstract: The condition of adsorbing gelatine by dialdehyde cellulose was investigated, and the adsorption product was analyzed with FT-IR spectrometry and thermogravimetry. The result shows that the optimum absorption conditions are pH value 8 and 40℃.The adsorption capacity increases with raise of time and oxidation degree, and reaches balance in 4h.The adsorption capacity is almost steady when oxidation degree is over 100%.The adsorption peaks of adsorption producthas characteristic of Schiff base in the FT-IR spectra. The initiative thermal degradation temperature rises with increase of adsorption capability.
