The optimized velocity of flow in dynamic adsorption is tenth of the volume of the resin columniation per minute and the adsorbed volume of the solution which contain 101μg/ml activity component of 2507 is 65 time of the volume of the resin columniation. The dynamic adsorption capacity of per gram resin is 9494μg/g, and the adsorption rate is almost 100％ because the hydrogen bond may be formed in the adsorption process.

动态吸附最佳的吸附流速为每分钟十分之一个柱体积，在此条件下，可以吸附相当于约65个柱体积的有效组分浓度为101μg／ml的溶液，每克树脂的动态吸附量为9494μg／g，因为可能在吸附过程中有氢键生成，所以吸附率几乎为100％。
