摘　　要：为了寻求快速、准确和高效的吸附等温线测定方法应用于色谱技术规模化精细分离氨基酸类物质的有效成分过程中,采用人工补偿逆方法进行L-苯丙氨酸的吸附等温线测定。与前沿分析法测定进行比较结果表明:二者结论基本相符。人工补偿逆方法减少了试验数量和目标样品使用量,缩短了试验时间,节约了成本,可以作为氨基酸类产品测定吸附等温线的一种精确、高效方法。In order to find a quick ,auccurate and high performance method to determine the adsorptior isotherms during the process of seperating aminoacid productions by chromatography technology, the inverse method of artificial compensation is adopted for determination of adsorption isotherms of L-phenylalanine. By comparing with frontal analysis method, the results show that：two methods are almost the same. In the inverse method of artificial compensation,the quartites of experiments and object samples are reduced,the test time is shorter, and the cost is saved, which can be taken as an accurate and high performance method for deteronination of adsorption isotherms of aminoacid productions.
