More has yet to be indicated on the ability of microphyte plants for the removal of heavy metals from contaminated environments. In the present research, the ability of the aquatic macrophyte, Typha domingensis species, for the phytoremediation of heavy metals (Zn, Cd, Ni, Pb, and Cr) in aqueous solution was investigated. Accordingly, 50 plants of T. domingensis species were harvested from Shadegan International Wetland, Iran. The plants were then translocated in the aquariums containing water contaminated with heavy metals (Zn, Cd, Ni, Pb, Cr) at concentrations between 0 (as control) and 20 mg L⁻¹ in two different pHs (4 and 7) for 30 days. Plant absorption of heavy metals, determined for different plant tissues, increased with increase in heavy metal concentration and decrease in water pH. The highest total uptake of heavy metals was in the following order: Zn (77.5%) > Pb (70.2%) > Ni (63.1%) > Cr (47.8%) > Cd (38.2%), with the order tissue of roots > stems > leaves > flowers. Plant roots had the highest values of bioconcentration (BCF) factor for Zn (2.16) > Pb (1.66) > Ni (1.46) > Cr (1.09) > Cd (0.94). However, compared with the leaves and flowers, plant aerial parts indicated the highest TF values, by the following order: Zn (0.95) > Pb (0.94) > Ni (0.90) > Cr (0.85) > Cd (0.79). T. domingensis is a heavy metal hyperaccumulator and can be efficiently used for the phytoremediation of aqueous solutions, contaminated with heavy metals including Zn, Pb, Ni, Cr, and Cd.

关于微型植物从污染环境中去除重金属的能力还有待进一步研究。在本研究中，研究了水生植物香蒲属植物修复水溶液中重金属（Zn、Cd、Ni、Pb 和 Cr）的能力。因此，从伊朗 Shadegan 国际湿地收获了50 株T. domingensis物种。然后将植物转移到含有被重金属（Zn、Cd、Ni、Pb、Cr）污染的水的水族箱中，浓度在 0（作为对照）和 20 mg L ^-1之间在两种不同的 pH 值（4 和 7）中 30 天。植物对不同植物组织对重金属的吸收随着重金属浓度的增加和水的 pH 值的降低而增加。重金属总吸收量最高的顺序为：Zn（77.5%）> Pb（70.2%）> Ni（63.1%）> Cr（47.8%）> Cd（38.2%），根组织>茎>叶>花。植物根系的生物富集 (BCF) 因子值最高，为 Zn (2.16) > Pb (1.66) > Ni (1.46) > Cr (1.09) > Cd (0.94)。然而，与叶和花相比，植物地上部分的TF值最高，顺序如下：Zn（0.95）> Pb（0.94）> Ni（0.90）> Cr（0.85）> Cd（0.79）。T. domingensis 是一种重金属超富集植物，可有效用于水溶液的植物修复，被包括 Zn、Pb、Ni、Cr 和 Cd 在内的重金属污染。
