The linear velation was good.The averagerecovery of chlorogenic acid was 98.98%,RSD was 0.83%.

本方法线良好,绿原酸的平均回收率为98.98%,RSD为0.83%。

The biological stability(assessed by AOC), had close relation to tannin value, and was increasing with the tannin value, but it had no velation to the pore size distribution.

滤出水的生物稳定与单宁酸值有，单宁酸值越低，出水的生物稳定越高，与孔径的分布则没有。
