Abstract

Waste-water from domestic use and from industrial effluent burden the water systems with high levels of heavy metal hence there is need to remove these heavy metals so that the waste water can be recycled for use for household or irrigation. The present study has screened Zea mays (maize), Commelina bengelensis (wondering jew), Helianthus annuus (sunflower) and Amaranthus hybridus (amaranthus) for their ability to bioaccumulate Pb, Cu, Cd and Zn metals. The results obtained show that the H. annuus and C. bengelensis plant have promising potential for removal of Pb, Cu and Cd from wastewater though their ability to remove Zn from contaminated solutions is not much different from that of Z. mays and A. hybridus.
玉米、山毛草、向日葵和苋属植物修复废水的潜力
来自家庭用水和工业废水的重金属含量很高,给水系统造成负担,因此需要去除这些重金属,以便废水可以循环使用,用于家庭或灌溉。本研究筛选了玉米(Zea mays)、麻豆(Commelina bengelensis)、向日葵(Helianthus annuus)和苋菜(Amaranthus hybridus)对Pb、Cu、Cd和Zn金属的生物富集能力。结果表明,黄杨和C. bengelensis对废水中Pb、Cu和Cd的去除能力与Z. mays和A. hybridus差异不大,但对废水中Zn的去除能力有很大的潜力。
