摘要
通过正交试验方法,用硅胶负载壳聚糖对直接耐晒兰、直接大红、直接艳红、直接深蓝、直接嫩黄五种水溶性染料进行脱色实验.对脱色的影响因素,如处理剂用量、pH值、搅拌时间、静置时间、染料颜色进行了探讨 确定了影响脱色效果的主次因素顺序,并绘制出硅胶负载壳聚糖对五种直接染料的吸附等温线,吸附等温线符合弗里德利希方程式 对直接耐晒兰的吸附方程式为:Γ=0.05·C0.
The paper presents a study of the decoloration of five direct dyes with chitosan supported by silicagel, and a discussion of several factors such as the amount of agents , pH value, stirring time, settling time ,and the color of dyes on the effect of decoloration. The adsorption isotherms of the five direct dyes on chitosan supported by silicagel were fit to Freundlich equations.
