“…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.…”

“…Azo dyes are extensively used in the dyeing process. The e uent containing dyes released into the surrounding thereby seriously affecting the atmosphere by destroying the ecosystem, causing water pollution, and reducing light penetration for aquatic life [3].Due to textile dye wastewater, the Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), suspended solid values enhance [4]. So, there is a big challenge to treat textile dyes e uent before released into water bodies.…”

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.

“…Phytoremediation features many advantages, such as environmental friendliness, easy application and low-cost maintenance, good efficiency, high aesthetic value and applicability to a variety of pollutants. Moreover, phytoremediation can be easily implemented in situ, addition to its low cost (Aransiola et al, 2013;Imron et al, 2019b).…”

This research analyses the performance of bacteria-assisted phytoremediation of aluminium (Al)-contaminated soil using native Indonesian plants namely, Scirpus grossus and Thypa angustifolia. A range finding test (RFT) was carried out for 14 days to obtain the tolerable Al concentration for both plants. A total of 2% and 5% (v/v) of Vibrio alginolyticus were bioaugmented during the 28-day phytoremediation test to enhance the overall Al removal. Result of the RFT showed that both plants can tolerate up to 500 mg/kg Al concentration. The addition of V. alginolyticus to the reactors resulted in a significant increment of Al removal from the contaminated soil (p < 0.05). Such addition of V. alginolyticus increased the Al removal by up to 14.0% compared with that withoutbacteria addition. The highest Al removal was obtained for S. grossus with 5% V. alginolyticus with an efficiency of 35.1% from 500 mg/kg initial concertation. T. angustifolia with 500 mg/kg initial concentration showed the highest removal of 26.2% by the addition of 5% V. alginolyticus. The increase of Al removal by the bioaugmentation of V. alginolyticus was due to the interaction in the plant's rhizosphere. Exudates of both plants provided a good environment for bacteria to live in the root area. Meanwhile, the bacteria increased the bioavailability of Al to be further extracted by plants. Certain mechanisms, such as rhizostabilisation, phytostimulation and phytoextraction, were considered to be the main processes that occurred during the treatment. S. grossus and T. angustifolia displayed promising ability to act as Al hyperaccumulators with bioaccumulation factor values up to 5.308 and 3.068, respectively. Development of the design of the ex-situ soil phytoremediation reactors is suggested as a future research direction because it can significantly enhance the current obtained finding.

“…Many studies have been conducted to examine various methods for the MB removal such as electrocoagulation (Golder et al 2005 Alternatively, phytoremediation is a process that uses different kinds of plants to remove contaminants, for example, a study conducted by Imron et al (2019) showed successful phytoremediation of MB using duckweed (Lemna minor).…”

Dyes are considered to be hazardous, have low biodegradability and can affect the human health as well as the aquatic life cycle. This research investigated the methylene blue (MB) removal using an activated carbon matrix of Scirpus grouss (waste that was initially used for phytoremediation of soil). The experiment was conducted in a flask containing 0.5 g AC-SC with MB concentrations of 5 and 15 mg/L. The adsorption was monitored for 120 sec. The results showed complete removal of MB within a contact time of 30 sec using 6-AC. The surface morphology analysis showed that at 6-AC, the structure was more porous. The ultimate potential of activated carbon prepared from the phytoremediation plant waste would be the best alternative for the water and wastewater treatment, while it provides an alternative to the phytoremediation waste management process.
