摘要
采用大孔吸附树脂对红花红色素进行精制,并对大孔吸附树脂进行了优选;研究了不同条件下X-5树脂对红花红色素的吸附和解吸性能.结果表明:X-5树脂对红花红色素具有良好的吸附和解吸性能,其吸附效果在室温、pH 7.0～9.0的条件下较好;采用pH 7.0～9.0、60%乙醇溶液进行洗脱,解吸效果较好.
The carthamin was refined from safflower with macroporous adsorption resins and the best macroporous adsorption resins were selected. The performances of X-5 resin in adsorption and desorption for carthamin from safflower were investigated under different conditions. The results show that X-5 resin has good characteristics in adsorption and desorption, with a better adsorption at room temperature and pH 7-9, and with a better desorption when it was eluted by 60%, ethanol at pH 7-9.
