介绍了氨基酸在固体表面吸附的常见吸附模式和吸附等温线类型。在常见的等温式中Sips等温式能处理液相中吸附质浓度从低到高、吸附剂表面从均匀到不均匀等各种情形下的固/液吸附体系,得到的等温线一般归属4类：S型、L型、H型和C型;总结和讨论了各吸附参数对氨基酸吸附的影响,具体考察了氨基酸种类、固体表面的性质、溶剂种类、介质的pH、介质离子强度和温度等因素对氨基酸吸附的影响,指出通过优化各吸附参数,可以调整氨基酸和固体吸附剂之间的静电吸引力或疏水作用,达到最好的吸附效果;对氨基酸的固体吸附剂进行了分类阐述。

英文摘要：

The types of adsorption models and isotherms of amino acids on the surface of solid materials are presented. The Sips isotherm equation has proved successful in modeling adsorption of solutes at low or high concentrations onto homogeneous or heterogeneous adsorbents. Commonly, the adsorption isotherm belongs to the one of S, L, H and C types. The influence of adsorption parameters is summarized and discussed. It is found that the adsorption is mainly impacted by the factors such as the types of amino acids, the surface properties of solid materials, the kinds of solvents, the pH values of solution, the ion strengths of solution and the temperature of adsorption system. Obviously, the adsorption capacity can achieve the maximum under the favorable electrostatic or hydrophobic interactions between the amino acids and the surface of solid materials, via optimizing the values of adsorption parameters. In addition, the classified solid materials for amino acids adsorption are introduced.
