研究了用树脂吸附和分离玫瑰李红色素,实验结果表明:X-5树脂对玫瑰李红色素的吸附效果最好。被吸附的玫瑰李红色素用70%的乙醇溶液洗脱,流速为1.4BV/min。X-5树脂非常稳定,使用22次后,其吸附能力无明显减弱。
The adsorption and separation of rose plum pigment with resin were studied. The experimental results show that X-5 resin has the best adsorption effect on rose plum pigment. Adsorbed rose red pigment with 70% ethanol solution, the flow rate of 1.4BV / min. X-5 resin is very stable, the use of 22 times, no significant reduction in its adsorption capacity.
