【 摘 要 】

This article is devoted to the experimental identification of the copper ions (II) uptake by the remediation plant. Wheat and barley were used as plants for phytoremediation. They were cultivated in the aqueous culture on the Hellriegel nutritive medium prepared without phosphorus. The copper was dissolved in the medium in the concentration 0 mg/l (control variant), 0.5 mg/l, 1.0 mg/l, 2.5 mg/l, 5 mg/l, 10 mg/l, 20 mg/l. The concentrations of the copper were identified in solutions by the ion meter in 2 weeks of cultivation. The moving arrangement with a plant as a biological bed is elaborated for phytofiltration. That is a technology for decontamination and final treatment of the wastewater from pollutants using plants. Particularly it is possible to remove ions of heavy metals. The device will be inexpensive, simple and easy for exploitation at the enterprise. It is offered to complete standard rectangular settler by the mentioned device.
