摘　　要：采用7种国产离子交换树脂:D61、D001-cc、001×7、D113、201×4、D301R、D418,对从啤酒废酵母中提取的谷胱甘肽溶液进行吸附分离,研究pH、吸附时间和原料浓度对谷胱甘肽吸附量的影响,筛选出两种吸附容量较高的树脂:D001-cc和D301R。Seven domestic ion-exchange resins including D61, D001-cc, 001 ×7, D113, 201 ×4, D301R and D418,were used for the separation of glutathione extracted from waste beer yeasts. The effects of pH, adsorption time and initial concentration on the adsorption capacity of glutathione were investigated. Two optimal ionexchange resins, D001-cc and D301R, with relatively high capacity were selected for the adsorption of GSH.
