The aim of this study is to investigate and develop a phytoremediation method for the removal of two triphenylmethane dyes (crystal violet and malachite green) using plant Eucalyptus species. The effects of operational parameters, such as plant quantity, initial dye concentration, initial pH of the solutions and temperature of the medium were studied in order to determine the optimum phytoremediation conditions. The plant’s photosynthetic pigments were de-termined quantitatively in order to detect its response to abiotic stress. During the phytoremediation experiments the pa-rallel sub-processes (phytoextraction, phytodegradation) were observed and analysed. The mechanisms of phytoreme-diation were studied using Fourier transformation infrared spectroscopy, ultraviolet-visible spectroscopy, thin layer chromatography. Results show that the plant tolerated high concentrations (300 mg/L) of dyes. It was able to remove the dyes from the environment and to accumulate them in its cells for up to a significant percentage (crystal violet was removed by about 80% and malachite green by 90%).
