Abstract
This paper studied the purifying efficiency of Alternanthera Philoxeroides and the activity of CAT,MDA contents in nutrition solution containing Zn 2+ through static test of laboratory experiment.The results showed that Alternanthera Philoxeroides had high purification ability in Zn 2+ polluted water.Accumulation of Zn i n roots and stems is higher than that i n leaves.With the rise of contents of Zn 2+ the activity of CAT in leaves ascended,while MDA contents descended.
