  • 摘要: 为了探讨紫根水葫芦对污水中重金属(镉、锌、铅)的净化效果,比较了普通水葫芦和紫根水葫芦的生物过滤能力和积累情况。实验结果显示,2种水葫芦均能显著降低3种重金属的含量,被吸收的重金属会在植物体内得到积累,且主要富集于根部,而不是茎叶部。此外,被吸收的重金属绝大多数不会重新释放到水体中。紫根水葫芦对重金属的净化效果优于普通水葫芦。因此,紫根水葫芦具有良好的水体修复和去除重金属的潜力。
    Abstract: To investigate the purification capability of purple root water hyacinth by eliminating heavy metals (cadmium, zinc and lead), biofiltration and bioaccumulation of purple root water hyacinth were compared with normal water hyacinth. The results showed that both water hyacinths significantly reduced the three heavy metals concentrations, accumulating these absorbed heavy metals inside the plant. The heavy metals were enriched mostly in roots rather than stems and leaves. Most of the absorbed heavy metals could not be released to the growth solution again. Purple root water hyacinth had higher capability on heavy metal purification than normal water hyacinth. Therefore, purple root water hyacinth has good potential for water remediation and heavy metal removal.
