| 中文摘要: |
| 为纯化盐地碱蓬红色素，提高其色价，选取 X-5、HPD300、D101、HPD400、NKA-9 和 AB-8 等 6 种
大孔树脂对盐地碱蓬红色素进行静态吸附试验，筛选最佳纯化色素树脂，并研究最佳树脂对盐地碱蓬红色素
的纯化工艺条件。结果表明，X-5 大孔树脂对盐地碱蓬红色素的吸附和解吸效果较好。在动态吸附中，当上样液
浓度为 1 mg/mL、pH 值为 6、流速为 5 BV/h 时，X-5 对盐地碱蓬红色素吸附效果最好；以 60%乙醇溶液为洗脱
剂，洗脱流速为 5 BV/h 时，解吸效果最好；盐地碱蓬红色素纯化后，色价提高了 6.14 倍。 |
| 英文摘要: |
| To elevate the red pigment from Suaeda salsa color value, the characteristics of static adsorption and desorption of six kinds of macroporous resins (X-5, HPD300, D101, HPD400, NKA-9, and AB-8) to red pigmentfrom S. salsa were investigated. The purification processes conditions of the best macroporous resin for red pigmentfrom S. salsa were also studied. The result indicated that X-5 resin was suitable for purifying red pigment from S.salsa. The appropriate dynamic conditions were liquid concentration 1 mg/mL, pH value 6, and flow rate 5 BV/h. Andusing 60% ethanol as effluent at 5 BV/h in speed, after purification, the color value of purified pigment was 6.14times higher than the original one. |
