Phytoremediation potential of water hyacinth in heavy metal removal in chromium and lead contaminated water

Use of <i>Eichhornia Crassipes</i> as a Bioadsorbent for the Removal of Methyl Orange and Methylene Blue Present in Residual Solutions

“…Industries such as cosmetics, food, biomedicine, paper, and textiles use dyes to produce their products generating around 10 thousand tons/year of waste [Uddin et al, 2021;Amalraj et al, 2021;Kadhom et al, 2020]. This has caused several problems due to toxicity, low biodegradation on the entire ecosystem around this discharge of the dyes due to their direct interference in the photosynthesis process, in addition to causing various diseases to humans in the skin and respiratory system [Panneerselvam et al, 2021;Marquez et al, 2021;Amalraj et al, 2021;Bożęcka et al, 2021]. Dyes are divided into anionic (acid dyes), nonionic (dispersed) and cationic (basic dyes), among them are methyl orange (MO) and methylene blue (MB) which have a similar molecular mass [Kadhom et al, 2020;Lacin et al, 2020;Uddin et al 2021].…”

“…There are conventional adsorbents such as clays, zeolites, low-cost and high-abundance mesoporous materials, however, the search for new materials that have a similar adsorption capacity and a high removal percentage has been carried out in recent decades [Lacin et al, 2020;Márquez et al, 2021;Amalraj et al, 2021], The agro-industrial waste have a very low cost such as peanut shells, wheat, tamarind, rice, orange, egg, walnut, etc., have been shown to have a removal capacity very similar to conventional adsorbents for the elimination of heavy metals, dyes, etc. [Saini et Within the management of plants for the adsorption process, one that has attracted attention is the Water Lily (Eichhornia crassipes), wich is a freshwater plant that floats freely in rivers, lakes, a lagoon that has high available due to its rapid growth and its great adaptability to many ecosystems, causing it to become an invasive species since it increases the evapotranspiration process and, interferes with human activities causing economic losses [Priya et al, 2017;Tabinda et al, 2019;Panneerselvam et al, 2021]. Several strategies (chemical and biological) have been used to eliminate the weed but it is very difficult to eradicate, since its seeds remain feasible for a long period of time [Patel S. 2012;Tabinda et al, 2019;Panneerselvam et al, 2021].…”

On the other hand, the feasibility of taking advantage of this biomass for the processing of wastewater has recently been studied using biodsorption for the treatment of the effluent with heavy metals such as Cr, Pb, Cu, etc..…”

Treatment of Tanning Effluent Using Seaweeds and Reduction of Environmental Contamination

“…is technique not only treats the effluent but also uses it to produce useful byproducts like agar gel by the Nikansui method. In the soak effluent having basic parameters like TDS, turbidity was found to be in a high range [17,18]. For treating this effluent, the conventional methods are suitable but not an economical one.…”

Water decolourisation using a phytoremediation method: Ocimum basilicum as model

“…This method is classified as eco-friendly and low-cost because it is driven by solar energy and is applicable to large or small volumes of wastewaters [15]. The previous literature shows many plants were used for the remediation of wastewaters from dyes; these plants included Fimbristylises, Ammannias, Phragmites, Bacopa monnieri Pennell, Tagetes patula, Lemna minor, Sweet Basil, and Eichhornia crassipes [5,[16][17][18]; also the phytoremediation method was used to remove other pollutants [19][20][21][22]. For example, Chandanshive et al [5] also used the phytoremediation method to remove dyes from solutions.…”
