Potentials of Salicaceae Plants for Phytoremediation of Cyanide
摘要
Abstract
The potential of woody plants from the Salicaceae family to degrade cyanide was investigated. Pre-rooted trees were grown in the laboratory in spiked hydroponic solution. Initial cyanide concentrations were 0.45 to 0.49 mg/L.Samples were directly taken from the solution and the cyanide concentrations were determined sectrophotometrically.The removal rate of cyanide from the aqueous solution by trees varied with plant species. The highest cyanide elimination exposure. The results indicate that a large proportion of cyanide can be removed from a contaminated aqueous medium through metabolism by trees. Doses (≤0.49 mg/L) used in this study were not toxic to the tested trees. Cyanide removal processes from hydroponic solution by trees followed zero order reaction. In conclusion, cyanide removal from cyanide-contaminated wastewater by plants seems to be a feasible option.关键词
