“…The presence of K-X ray of peaks of Cd in the treated spectrum (Figure 5(b)) indicates the extraction of the heavy metal Cd by C. vulgaris from textile effluent and reduction in pollution load of textile effluents. Similar study of extraction of heavy metal Cd by C. vulgaris from polluted river water was also reported by Laffont-Schwob et al [32]. The potential applications of C. vulgaris for metal removal of effluent have also been reported earlier [38].…”

“…Temperature of textile effluent was recorded as 46°C at the time of collection, which was considered to be quite high. The optimum temperature required for the growth of macroalgae C. vulgaris ranges from 20°C to 35°C [32]. Hence, all phytoremediation experiments were carried out after one day of collection when temperature of the effluent came down to room temperature (30-34°C).…”

Textile effluent released into water bodies is prone to be toxic for aquatic flora and fauna. In the present study, the phytoremediation potential of Chara vulgaris (C. vulgaris) is investigated for treatment of textile effluent. The highly concentrated and toxic textile effluent is diluted to different concentrations 10%, 25%, 50%, and 75% to check the accessibility of macroalgae to bear pollutant load of textile effluent. The toxicity of textile effluent is analysed by determining different water quality parameters, namely, pH, TDS, BOD, COD, and EC. The maximum reductions in TDS (68%), COD (78%), BOD (82%), and EC (86%) were found in the 10% concentrated textile effluent after 120 h of treatment. The highly concentrated textile effluent showed its toxic effect on macroalgae and it was found unable to show a remarkable change in water quality parameters of 75% and 100% textile effluent. The correlation coefficient values are determined using correlation matrix to identify the high correlation between different water quality parameters. The removal of toxic organic pollutants by C. vulgaris was confirmed by using UV-visible absorption spectra. Typical X-ray spectra recorded using EDXRF technique indicated the presence of heavy metals Cd in the dried sample of macroalgae after treatment which show its capability to remove toxic heavy metals from textile effluent. The reliability model has been proposed for treated textile effluents to identify percentage level of toxicity tolerance of waste water by macroalgae.

“…For instance, heavy metal Arsenic was found to be absorbed by C. vulgaris in salty water lake (Fereshteh et al 2007). In another research report, C. vulgaris beds were reported for remediation of heavy metals such as Pb, Cd, Zn, and Cu in river water (Rai et al 1995;Laffont-Schwob et al 2015). In our earlier work, the phytoremediation capability of C. vulgaris was assessed for a carcinogenic basic azo Congo red dye and basic textile effluent (Mahajan and Kaushal 2013;Mahajan et al 2019).…”

Phytoremediation is an innovative, eco-friendly, and solar-driven technique, which becomes a well-known alternative solution for remediation of hazardous dyes from wastewater. In present research work, potential of a submerged fresh water macroalgae Chara vulgaris L. (C. vulgaris) examined for removal of acidic azo dye methyl red (MR) in its solution form. A series of experiments were done with C. vulgaris to predict the effects of different parameters viz. contact time, initial dye concentration, amount of macroalgae, and pH. The increase in initial dye concentration directly impacts on the potential of macroalgae. The decolorization percentage declined with increase in initial dye concentration. The equilibrium condition was found to achieve after contact time of approximately 48 h. The decolorization of MR dye was found to be favorable at pH 5. The macroalgae was successfully utilized repeatedly with MR for eight cycles in batch experiments. The kinetics of phytoremediation of MR dye was studied with help of pseudo-first-order, pseudo-second-order, and Elovich kinetic models and the results were well suited to pseudo-second-order kinetic model with the correlation value R 2 ≥ 0.99. In addition, the experimental data was also assessed by using Langmuir and Freundlich adsorption equilibrium isotherms. The results of phytoremediation data was found to be in favor of Freundlich equilibrium isotherm which having the correlation value R 2 ≥ 0.977. The intraparticle diffusion model also studied to interpret the macroalgae phytoremediation mechanism for phytoremediation of MR. The surface interactions of C. vulgaris were investigated before and after the removal of dye with Fourier transform-infrared spectroscopy (FTIR) technique. On the basis of these studies, a hypothetical mechanism has also been proposed to depict the phytoremediation of acidic azo dye by C. vulgaris.

“…Although the ecosystem components found in bays and inlets of the northern Baltic Sea are, to our knowledge, today not used as medicinal resources, there may be future potential. Charophytes may effectively remove organic chemicals, such as hexachlorobenzene (Schneider and Nizzetto 2012), and metals, such as uranium (Kalin et al 2005), nickel, cadmium, lead and zinc, from the water (Baker et al 2012, Gao and Yan 2012, Sooksawat et al 2013, Clabeaux et al 2013, Laffont-Schwob et al 2015. Charophytes may mitigate cyanobacterial blooms in surface waters (Pakdel et al 2013), reduce the viability of Pythium (a parasitic oomycete that can cause rotting of plant roots, Juan et al 2014), as well as reduce the development of benthic biofilms (Gette-Bouvarot et al 2015).…”
