“…Water hyacinth shows significance removal efficiency for Cd, Pb, Cu, Zn, Fe, As, Mn, Cr, As, Al and Hg as reported in different recent studies [180][181][182][183]. Shoot powder of water hyacinth removed Cr and Cu by 99.98% and 99.96% when exposed to tannery effluents [184]. Recent research studies conducted to check the removal efficiency of water hyacinth for heavy metals are given in Table 2.…”

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.

“…In addition, Sarkar et al reported that water hyacinth shoot powder could be a potential adsorbent for removal of Cr and Cu, with high adsorbent capacity of about 99% Cr and Cu from a standard solution (SS), as well as from tannery effluent (TE). 19 Jute is also an abundant agricultural waste, rich in cellulose and lignocelluloses, which has three hydroxyl groups at the anhydroglucose units of the cellulose backbone. Thus, it provides the possibility for application as adsorbent.…”

A new efficient anion adsorbent was fabricated by amino-grafting lignocellulose-rich jute stalk (AGJ) to uptake toxic hexavalent chromium (Cr(VI)) from aqueous solutions. Batch adsorption experiments were performed as a function of adsorbent dosage and initial solution pH to test the adsorption-coupled reduction for anion Cr(VI). Maximum chromium adsorption was found at pH 2.0 with an appropriate adsorbent dosage of 1.0 g/L. The adsorption equilibrium data were best described by the Langmuir isotherm model. The maximum monolayer adsorption capacity was 154.30 mg/g, evaluated using the Langmuir equation. The kinetic analysis revealed that the adsorption of Cr(VI) was fitted very well by the pseudo-second-order model during the whole adsorption process. The binding mechanism of chromium onto the AGJ surface was confirmed by Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) analyses. All the results in this study illustrated that AGJ could be considered as an economically viable and effective adsorbent for treatment of aqueous solutions contaminated with Cr(VI).

Copper is a commonly used metal in construction, engineering, agriculture and water treatment. Consequently, increased copper concentrations resulting in adverse environmental effects is inevitable. Phytoremediation using Dendrocalamus asper or Philippine giant bamboo (PGB) is a viable option for treatment of copper-contaminated media, but their copper uptake potential remains largely unexplored. As such, the copper uptake of PGB was evaluated under varying environmental conditions, namely initial copper concentration, water hardness and pH.Six-month old propagules were planted in artificially contaminated water in order to determine the copper uptake after 16 days of treatment. Using a Box-Behnken design of experiment, it was found that both initial copper concentration and pH have significant and proportional effects on copper uptake. However, due to possible speciation and/or competition, the optimum copper uptake occurred at 20 ppm Cu and pH 5 (as opposed to 7). A mathematical equation, bearing an R2 = 0.7097, was constructed as a possible model for copper uptake of PGB to understand when PGB phytoremediation is most effective. At copper concentrations lower than 3.81 ppm, higher pH is beneficial to copper uptake and vice versa. Overall, phytoremediation using D. asper or PGB is effective especially at low pH and elevated copper concentrations.
