研究了用树脂吸附和分离康乃馨红色素 ,比较了 4种树脂对康乃馨红色素的吸附。结果表明 ,四种树脂对康乃馨红色素的吸附效果均较好。本实验选用AB 8树脂作吸附剂。洗脱剂用 6 0 %的乙醇 ,洗脱效果好 ,产品杂质少 ,色价高 ,且使用 2 0次后其吸附性能稳定 ,所以选用AB 8树脂吸附康乃馨红色素
The adsorption and separation of carnation red pigment by resin were studied. The adsorption of carnation red pigment by four kinds of resins was compared. The results showed that all four resins adsorbed carnation red pigment better. AB 8 resin was chosen as adsorbent in this experiment. Eluent 60% ethanol, good elution, less impurities, high color value, and the use of 20 after its adsorption stability, so use AB 8 resin adsorption carnation red pigment
