摘　　要：运用4种吸附理论模型,即Langmuir、Freundlich、Redlich-Peterson和Nernst吸附模型,讨论了酸性染料在雄蚕丝上的吸附,研究了染色温度对吸附参数的影响.研究表明:Langmuir和Redlich-Peterson能很好地描述酸性染料在雄蚕丝上的吸附性质,酸性染料以离子键的形式在雄蚕丝上发生吸附.天龙蓝A2R在雄蚕丝上的吸附是典型的放热过程,Langmuir吸附常数KL随着染色温度的升高而降低.Four sorption models（Langmuir,Freundlich,Redlich-Peterson,Nernst） were applied to discuss the mechanism of the sorption of acid dyes on male silk.The influence of dyeing temperature on sorption parame-ters was investigated.The experimental data showed that Langmuir and Redlich-Peterson could well describe the sorption behavior of acid dyes on male silk.The interaction force between acid dyes and male silk was elec-trostatic attraction.The sorption process of Telon blue A2R was typical exothermic,Langmuir sorption constant KL decreased with the increase of dyeing temperature.
