| 摘 要： | 以D-101树脂为吸附材料，研究不同条件下对蛇莓果实红色素的吸附和解吸性能．研究发现：静态吸附中上样液温度为30℃时的吸附量较大；动态吸附中上样液酸度为0.5%，吸光度0.179~0.224， pH1.0，流速2 mL/min时的吸附量大；用80%乙醇以2 mL/min的流速进行洗脱时，解吸效果最好；蛇莓果实色素纯化后色价提高了3倍左右，该研究条件科学合理，纯化效果很好.

| Abstract: | A method for adsorption and desorption of the snake blackberry fruit pigment performance with D-101 macroporous resin was studied in different conditions. The results showed better performance for adsorption and desorption above the average sample liquid temperature 30℃. The appropriate dynamic condi-tions are：sample solution acidity is 0.5%, absorbance of pigments of sample is 0.179~0.224 and pH1, the ve-locity of flow is 2 mL/min;EtOH 80%is used as eluant and the velocity of flow is 2 mL/min. The colourity of pigments purification enhanced 3 times. In short, the study condition is rational and scientific, and the purifica-tion effect is very good. |
