Removal of aluminum by aquatic plants Ceratophyllum demersum and Chara fragilis from water of experimental ecosystems

Аннотация

Changes in the concentration of the aluminum ions in water of experimental systems (microcosms) have been studied. The Al ion concentration was measured by the fluorescent method. As macrophytes for microcosm incubation served hornwort Ceratophyllum demersum and stonewort Chara fragilis, with the latter hydrobiont used for the first time in similar experiments. It has been convincingly proven that, in the microcosms with the aquatic plants tested, the Al ion concentration decreased much faster than in the macrophyte-free control microcosms. The data obtained suggest that Ceratophyllum demersum and Chara fragilis are promising candidates for phytoremediation applications.
