摘　　要：采用室内培养方法,研究了玉米、豌豆、蓖麻和向日葵等4种作物种苗对水体中铜的去除作用。分析表明,在所选择的实验条件下,采用种苗过滤能够在96h内使水体中铜浓度显著降低。在蓖麻、向日葵、豌豆等植物幼苗的根部分别积累了21.5mg·g-1、24.3mg·g-1和8.96mg·g-1的铜,其茎、叶中也有一定量的铜积累。文章还对不同铜浓度下的实验结果进行了对比和讨论,提出选择一些传统作物种苗进行环境水体中铜污染的植物修复具有良好的应用前景。In this article,4kinds of crop seed lings were evaluated in removing of C u fromwater using blastofiltration method.At the selected experiment conditions,an alysis results showed that in 96hour s,the concentration of Cu decreased obviously.In the dry roots of castor -oil plant ?sunflower and pea,Cu can be accumulated to 21.5mg ·g -1 ,24.3mg ·g -1 and 8.96mg ·g -1 ,re-spectively.Some quantity of Cu can b e accumulated to the stems and leaves,too.The experiment results of different concentration of Cu have been discussed and the viewpoint was given that some of the traditional crop seedlings would have a good blastofiltration e-cological application prospects in the phytoremediation of Cu pollutio n in water.
