“…Reclamation of wastewater has been the only option left to meet the increasing demand of water in growing industrial and agricultural sectors [10].Industrial and domestic untreated wastewater contains pesticides, oils, dyes, phenol, cyanides, toxic organics, phosphorous, suspended solids, and heavy metals (HMs) [11]. Heavy metals among these toxic substances can easily be accumulated in the surrounding environment [12]. Commercial activities such as metal processing, mining, geothermal energy plants, automotive, paper, pesticide manufacturing, tanning, dying and plating are held responsible for global contamination of heavy metals [13,14].…”

Application of Floating Aquatic Plants in Phytoremediation of Heavy Metals Polluted Water: A Review

Heavy-metal (HM) pollution is considered a leading source of environmental contamination. Heavy-metal pollution in ground water poses a serious threat to human health and the aquatic ecosystem. Conventional treatment technologies to remove the pollutants from wastewater are usually costly, time-consuming, environmentally destructive, and mostly inefficient. Phytoremediation is a cost-effective green emerging technology with long-lasting applicability. The selection of plant species is the most significant aspect for successful phytoremediation. Aquatic plants hold steep efficiency for the removal of organic and inorganic pollutants. Water hyacinth (Eichhornia crassipes), water lettuce (Pistia stratiotes) and Duck weed (Lemna minor) along with some other aquatic plants are prominent metal accumulator plants for the remediation of heavy-metal polluted water. The phytoremediation potential of the aquatic plant can be further enhanced by the application of innovative approaches in phytoremediation. A summarizing review regarding the use of aquatic plants in phytoremediation is gathered in order to present the broad applicability of phytoremediation.

“…Industriële en huishoudelike afvalwater bevat onder andere pestisiede, olies, kleurstowwe, fenole, sianiede, toksiese organiese verbindings, fosfate, gesuspendeerde partikels en swaarmetale (Pakdel & Peighambardoust 2018). Kommersiële aktiwiteite, insluitend mynwese, geotermiese aanlegte, die motorbedryf, gifstofvervaardiging, leerlooiery, asook kleur en plateringsaktiwiteite, word wêreldwyd verantwoordelik gehou vir swaarmetale wat die omgewing kontamineer en wat eventueel in oppervlakwater akkumuleer (An et al, 2015;Peligro et al, 2016). Die eliminering van swaarmetale uit afvalwater is egter problematies omdat dit in verskillende chemiese vorme voorkom, dit nie biodegradeerbaar is nie en maklik deur verskillende trofiese vlakke beweeg om uiteindelik in die biota te akkumuleer.…”

“…The disadvantages of electrodialysis are that it requires high cost, highly trained human resources, as well as fouling and scaling of membranes. But most of these technologies are highly expensive and not very effective at lower Cr(VI) concentrations [5].…”

The usage of pig iron sludge nanoparticles as adsorbent was explored to remove Cr(VI) from effluents. Batch sorption was administered to check the effect of various parameters on the sorption method, namely, pH, interaction time, as well as Cr(VI) concentration and dosage. The adsorption potential was related with the parameters. An inovative flow chart was proposed by using this sludge, which is a byproduct from the pig iron manufacturing industries, as adsorbent for the treatment of Cr(IV)‐contaminated water, and then this sludge is recycled for drying followed by filtration. The adsorbed Cr(VI) will be useful for producing steel in a blast furnace. The sorption followed a second‐order mechanism and the experimental data obeyed the Langmuir adsorption isotherm. Surface diffusion was found to be the sluggish step and thus is the rate‐limiting step.
