1 引言 亲和吸附是纯化蛋白质等生物大分子物质最有效的分离方法之一,现已有多种形式,如亲和色谱、高效亲和色谱及高效免疫亲和色谱(High-performance ImmunoaffinityChromatography,简称HPIAC)等,它在工业中的应用还只是刚刚起步,目前从工程角度对其认识还很不充分,而亲和吸附过程的优化和放大需要充分了解平衡关系,生物分子吸附等温线大多为非线性,除用Langmuir方程描述单克隆抗体系统的吸附平衡外,目前尚无公认的较全面地对亲和吸附平衡进行描述的模型。
补充资料:化学吸附
化学吸附 chemical adsorption 由于固体表面存在不均匀力场,表面上的原子往往还有剩余的成键能力,当气体分子碰撞到固体表面上时便与表面原子间发生电子的交换、转移或共有,形成吸附化学键的吸附作用。 吸附特点 与物理吸附相比,化学吸附主要有以下特点:①吸附所涉及的力与化学键力相当,比范德华力强得多。②吸附热近似等于反应热。③吸附是单分子层的。因此可用朗缪尔等温式描述,有时也可用弗罗因德利希公式描述。捷姆金吸附等温式只适用于化学吸附: 说明:补充资料仅用于学习参考,请勿用于其它任何用途。
