研究采用体外培养的方法，探究pH和纤维水平对苜蓿纤维吸附铜的影响。研究共分两个试验。试验一：采用2×7析因试验设计，设定两个（3.0和5.5）pH水平及7个铜离子水平；试验二：采用4×7析因试验设计，设定0.125、0.25、0.5和1 g·mL-1的4个纤维水平及7个铜离子水平。体外39℃培养24 h。与pH 3.0相比，pH5.5时的铜离子被纤维吸附的比率更高（P＜0.05）；随着纤维水平的增加，纤维吸附铜离子的比率和吸附量逐渐提高（P＜0.05）。因此得出结论：在pH3.0~5.5条件下，pH越低，苜蓿纤维对铜的吸附性越强；纤维水平越高，纤维对铜的吸附性越强。

The objective of the study was to investigate the effects of pH and fiber level on absorption of copper to alfafa fiber in vitro. In experiment 1,the absorption of copper to alfalfa fiber under pH(3.0 or 5.5)was determined with 7 copper concentrations in 2×7 factorial design. In experiment 2,the absorption of copper to alfalfa fiber under 4 fiber level (0.125,0.25,0.5,1 g·mL-1)was determined with 7 copper concentrations in 4 ×7 factorial design. Comparing with absorption rate of copper to alfalfa fiber under pH 3.0,the absorption rate of copper to alfalfa fiber was higher under pH 5.5 (P<0.05). With the increased fiber level,the absorption rate or amount of copper to alfalfa fiber increased gradually (P<0.05). Under the condition of pH 3.0-5.5,the pH was lower,and the absorption ability of copper to alfalfa fiber was the higher. The level fiber was higher,and the absorption ability of copper was higher.
