“…The plant C. roseus able to bear the toxic impact of dyes but the rate of decolourisation is quite slow for both MB and CR dyes. In the preceding work, the removal of MB was also reported through phytoremediation process with the help of aquatic plant Eichhornia crassipes and Lemna minor [40,3]. The researcher reported that E.…”

Most of the dyes are carcinogenic and mutagenic in nature. Plants are potential candidates to remediate textile dye wastewater from contaminated sites. The present study aimed toscreen potential plant species for removal of synthetic dye solution of triarylmethane dye Methylene Blue (MB) and diazo dye Congo Red (CR). Six plant species were screened for their phytoremediation ability for the removal of dyes present in synthetic wastewater. Six plants selected for screening areTrachyspermum ammi L. (T. ammi), Tagetes erecta L. (T. erecta), Hibiscus rosa-sinensis L. (H. rosa- sinensis), Chrysanthemum indicum L. (C. indicum), Bryophyllum fedtschenkoi (B. fedtschenkoi), Catharanthus roseus L. (C. roseus). The phytotreatment of dyes was done up to 40 hfortwo different concentrations of dyes 10 mg L− 1 and 20 mg L− 1. Among these plants, the maximum decolouration was obtained from T. ammi plant followed by B. fedtschenkoi plant. Both of these plants showed active growth even after the phytoremediation process. T. ammi decolourised the MB dye 99% (10 mg L− 1) and 86% (20 mg L− 1) while the decolourisation of the CR dye solution was up to 95% (10 mg L− 1) and 84% (20 mg L− 1).T. ammi found to have maximum potential among screened plants for the removal of MB and CR dye from synthetic dye solution and can be used for decolouration of synthetic dye wastewater.

“…It can grow up to 20 cm long and the fern colour is light green to medium green colour, with brownish edges when mature 31 . Much research deals with floating plants, which are highly tolerable to many environmental contaminants, such as heavy metals and hydrocarbons 32,33 , but few studies have shown that the plants have the ability to biodecolorize textile dyes 2,34 . In the present study, the aim of this research was to explore the ability of Salvinia molesta to decolourize MO dye in synthetic wastewater.…”

In the present study, the potential of Salvinia molesta for biodecolorization of methyl orange (MO) dye from water was examined. Six glass vessels were filled with 4 L of water contaminated with MO with three concentrations (5, 15, and 25 mg/L), three with plants and another three without plant as contaminant control. The influence of operational parameters, including initial dye concentration, pH, temperature, and plant growth, on the efficacy of the biodecolorization process by S. molesta was determined. Temperature and pH was in the range of 25–26 °C and 6.3 to 7.3, respectively. Phytotransformation was monitored after 10 days through Fourier transform infrared (FTIR) spectroscopy, and a significant variation in the peak positions was demonstrated when compared to the control plant spectrum, indicating the adsorption of MO. The highest biodecolorization was 42% in a 5 mg/L MO dye concentration at pH 7.3 and at 27 °C. According to the FTIR results, a potential method for the biodecolourization of MO dye by S. molesta was proven. Salvinia molesta can be successfully used for upcoming eco-friendly phytoremediation purposes for dye removal.

“…They are ideal plants for phytoremediation because both plants can proliferate to a large extent, and they are known to develop rapidly and in an invasive manner, covering the surface of the water to prevent sunlight from entering the lower layers of water, thereby preventing the spread of photosynthetic plants in the lower layers [13][14][15][16][17]. E. crassipes is considered as the ideal water plant for rhizofiltration of noxious elements and is accepted worldwide in treating wastewaters, being infamous for its fast, uncontrolled growth, its high tolerance to pollutions, and its capability to uptake heavy metals and persistent organic pollutants together with nutrients [14,18,19]. As researchers have shown, Salvinia sp.…”

Organic pollutants, such as dyes, have a negative effect on the aqueous environment, therefore, their elimination from water bodies is a high priority. In this work, Eichhornia crassipes and Salvinia natans, both model plants with high phytoremediation efficiency, were exposed to various concentrations (Ci = 50–500 mg/L) of Eriochrome Black T (EBT). Their capacity to assimilate EBT was studied for 16 days of exposure, similar to natural conditions and by spectrophotometric monitoring of the dye concentration (EE. crassipes; 150 mg/L = 33%; ES. natans; 150 mg/L = 71.5%). The changes of the experimental parameters (pH—equalised by day 5, temperature, humidity, light intensity) were followed, and plant growth and biochemical responses to toxic stress effects (photosynthetic pigments, Energy-dispersive X-ray spectroscopy (EDX)—decreased effect of P, Mg, Ca, S and K, Scanning electron microscopy (SEM), defense enzyme) were examined. Furthermore, changes in oxidative- and photo-degradation of EBT in time and the solid-state properties (SEM, EDX, Fourier-transform infrared spectroscopy-FTIR) of the dye were investigated. Our results demonstrate that, despite the toxic stress, both species succeeded in reducing the dye-concentration of the water and S. natans proved to be more efficient in binding and removing organic dyes. With our findings, we proved that both plants alleviated the abiotic stress of dye contamination.
