“…From Table , the lowest value of h MTZ and the highest value of %Rem t were obtained in the breakthrough curve at the inlet concentration of 1.0 mmol L –1 . Similar results were reported in the literature showing that biosorption of copper in fixed bed is favored at lower inlet concentrations. ,, Furthermore, the values of biosorption capacity increased with increasing the inlet concentration from 1.0 to 1.5 mmol L –1 , but they decreased when the inlet concentration of copper increased to 2.0 mmol L –1 . These results suggest that the range of inlet concentration for obtaining higher copper removal is between 1.0 and 1.5 mmol L –1 .…”

The aim of this work is to investigate the biosorption of Cu(II) by an acidified waste product from the alginate extraction of algae in batch system and fixed bed columns. The results showed that the maximum copper biosorption capacity verified for the acidified biosorbent at 313 K was 3.580 mmol g −1 and equilibrium isotherms were best described by the Dubinin−Radushkevich model. Thermodynamic analysis showed that the process presented positive values of biosorption enthalpy (22.91 kJ mol −1 ) and biosorption entropy (114.98 J mol −1 K −1 ), indicating that the process is endothermic with dissociative mechanisms. Fixed bed experiments provided a higher percentage removal of copper at the feed flow rate of 0.5 mL min −1 and the inlet concentration of 1.0 mmol L −1 . Column data were best described by the Yan et al. model. Copper desorption was performed using four different eluents. Among the eluents, HNO 3 presented the highest value of elution efficiency in batch system.

These disadvantages have encouraged researchers to look at cost‐effective alternative technologies to treat metal‐contaminated waste streams (Calero et al, 2011; Feng et al, 2011; Gorka et al, 2011; Ghaedi et al, 2013; Xu et al, 2013). Recently, the use of environmentally friendly materials for the elimination of diluted heavy metals from large volume streams has attracted significant interest.…”

The removal of heavy metals, especially from wastewater, has attracted significant interest because of their toxicity, tendency to bioaccumulate, and the threat they pose to human life and the environment. Many low-cost sorbents have been investigated for their biosorption capacity toward heavy metals. However, there are no reports available on the removal of Pb(II) from aqueous solution by of Jatropha curcas L. seed husk ash. In this work, use of J. curcas seed husk ash for the removal of Pb(II) from wastewater was investigated as a function of contact time and the initial pH of the solution. Kinetics and equilibrium constants were obtained from batch experiments. Our study shows that the adsorption process follows pseudo-second-order kinetics. Moreover, the Langmuir absorption model gave a better fit to the experimental data than the Freundlich equation. The maximum adsorption capacity of the husk ash was 263.10 mg g −1 at 298 K and pH 5.0, and this is higher than the previously reported data obtained using other sorbents. The results obtained confirm that J. curcas seed husk ash is an effective sorbent for the removal of Pb(II) from aqueous solution. Analysis of infrared spectra of the husk ash after absorption of Pb(II) suggested that OH, C=O, C-O, Si-OSi, and O-Si-O groups were important for the Pb(II) ion removal. Moreover, practical tests on this biosorbent for Pb(II) removal in real wastewater samples successfully demonstrated that J. curcas seed husk ash constitutes an efficient and cost-effective technology for the elimination of heavy metals from industrial effluent. Removal of Lead(II) Ions from Aqueous Solution Using Jatropha curcas L. Seed Husk Ash as a BiosorbentBingfang Shi,* Weiyuan Zuo, Jinlei Zhang, Haijuan Tong, and Jinhe Zhao T here is considerable concern about contamination of the environment by heavy metals because of their toxicity and the threat they pose to humans and aquatic ecosystems (Alavi et al., 2015). Because of rapid industrial development and increasing manufacture of chemicals, large amounts of aqueous effluent containing heavy metals are discharged into the environment (Babel and Kumiawan 2003;Chojnacka 2010). The presence and accumulation of heavy metals in living organisms beyond permissible limits can result in various diseases and disorders (Liao et al., 2010). Lead(II) is one of the most widespread heavy metal contaminants in the environment. The most prominent and ubiquitous source of Pb(II) in the environment is industrial effluent from smelting, electroplating, mining, alloying, pigmenting, plastic manufacture, metallurgy, and refining (Farooq et al., 2010). The accumulation of large quantities of Pb(II) in humans can cause a range of negative health effects, from behavioral problems and learning disabilities to seizures and death (Bairagi et al., 2011;Yadav et al., 2014). Therefore, it is necessary to reduce the concentration of lead in industrial effluent before it is discharged into the environment.Conventional methods used to remove heavy metals from aque...

“…However, this method involves chemical consumption and increased sludge volume generation. In a word, these technologies demonstrate evident shortcomings, including inadequate removal of pollutants [32], high capital costs [33], considerable reagents or energy requirements [34], and generation of toxic sludge or other wastes requiring further safe disposal [35]. Adsorption is a common process in wastewater treatment technologies.…”

Red mud (RM) is an industrial waste produced in large amounts during alumina extraction from bauxite. Its disposal generates serious environmental pollution due to high alkalinity. Therefore, a strategy for the effective utilization of RM must be developed. For instance, RM may be transformed into useful products, such as adsorbents. Given its high concentrations of aluminum oxides, iron oxides, titanium oxides, silica oxides, and hydroxides, RM may be developed as a cheap adsorbent for the removal of various ions from aqueous solution and soils (e.g., metal and non-metal ions, phenolic compounds, and dyes) and waste gas purification (sulfide and carbide). This review summarizes the background, properties, and applications of RM as an adsorbent. Proper approaches of removing metal and non-metal elements from wastewater are also systematically reviewed and compared. Emphasis is placed on the surface modification of RM to obtain high adsorption. Finally, the scope for future research in this area for RM is discussed in depth.
