摘　　要：研究AB-8大孔吸附树脂对虾青素的静态、动态吸附效果。结果表明,AB-8树脂对虾青素的最大吸附量为476.2 μg/g干树脂,乙酸乙酯对虾青素的解吸率为98.7%;动态吸附条件为虾青素上样质量浓度2 μg/mL、上样流速4 BV/h。此条件下,皂化液中虾青素的回收率为78.9%,纯度为92.4%。In the present study, the static and dynamic adsorption capacities of AB-8 macroporous resins for astaxanthin from Antarctic krill shells were evaluated. The results showed that the maximum quantity of astaxanthin adsorbed was 476.2 μg per gram of dry AB-8. Ethyl acetate was selected as the elution solvent with a desorption rate of 98.7%. The dynamic adsorption conditions were optimized as 2 μg/mL and 4 BV/h for astaxanthin concentration and flow rate, respectively. Under the optimal condition, the astaxanthin in saponification solution was purified with recovery rate of 78.9% and purity of 92.4%.
