“…Wastewater treatment becomes a vital issue for developing countries in regards to the water as well as environmental securities. Conventional techniques such as solid-liquid extraction [8,9], liquid-liquid extraction [10,11], precipitation [12,13], and sorption [14,15] have been applied for heavy metals removal from aqueous solution. Although these technologies are frequently used, they have intrinsic disadvantages, e.g., high-energy requirements, byproduct formation, and high sludge production [3][4][5][6][7][8].…”

“…It is general knowledge that the adsorbent selection is critical to the adsorption behavior. Typical adsorbents like activated carbon and zeolite cannot keep up with the demand since they produce a lot of sludge during the removal process, limiting their adsorption impact [12][13][14]. As a result, developing a variety of unique, ecofriendly adsorbents to provide efficient heavy metals removal is of major importance.…”

Biomass-based solid residuals can be of serious hazardous environmental impacts if left for natural degradation. Thus, the proper utilization of such residuals is highly recommended. Therefore, one of solid residuals: namely, corn shell, was used in this study to synthesize carbon species (labeled as CS-C) as an adsorbent for efficient removal of heavy metal ions from aqueous solution. The structural properties and the textural characteristics of the prepared carbon species were verified. The present charges on the carbon surface were acquired via zeta potential analysis. The performance of CS-C, as adsorbent, was investigated through batch technique. Adsorption isotherm was optimally described using the Langmuir model reflecting that the removal process occurs at the homogenous surface of CS-C through a chemical reaction (surface complexation mechanism). The equilibrium state for the sorption process was reached after 4 h of interaction. The kinetic studies revealed the nice fit of heavy metal removal process to Pseudo-second-order model and the thermodynamics is matched to endothermic, spontaneous, and feasible sorption process. The displayed results could emphasize the high potentiality of CS-C to act as a remarkable sorbent for efficient tackling of water contaminants.

In the last decades, the idea of green nanotechnology has been expanding, and researchers are developing greener and more sustainable techniques for synthesizing nanoparticles (NPs). The major objectives are to fabricate NPs using simple, sustainable, and cost-effective procedures while avoiding the use of hazardous materials that are usually utilized as reducing or capping agents. Many biosources, including plants, bacteria, fungus, yeasts, and algae, have been used to fabricate NPs of various shapes and sizes. The authors of this study emphasized the most current studies for fabricating NPs from biosources and their applications in a wide range of fields. This review addressed studies that cover green techniques for synthesizing nanoparticles of Ag, Au, ZnO, CuO, Co3O4, Fe3O4, TiO2, NiO, Al2O3, Cr2O3, Sm2O3, CeO2, La2O3, and Y2O3. Also, their applications were taken under consideration and discussed.

Removal of industrial dyes and metals into water has been considered as a serious environmental problem. To solve this issue, in this study nickel hydroxide/polystyrene composites adsorbents were introduced for the water remediation from the harmful methylene blue dye and Fe (III). Polystyrene was obtained from its monomers using emulsion polymerization technique. The composite was obtained by precipitating nickel hydroxide from its solution on polymer surface by enhancing pH of the medium. The structural and morphological characteristics of the synthesized composites were investigated by Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), energetic dispersive X-ray (EDX), and x-ray diffraction (XRD). FT-IR spectra for composites showed the characteristic peaks of polystyrene and that correspond to hydroxide from NiOH2 (3442 cm -1 ). SEM analysis showed that the Ni(OH)2 were distributed on the surface of polystyrene in a regular manner. EDX analysis showed the presence of 19.9 wt% of Ni on the composite. XRD analysis showed the characteristic diffraction peaks at 2θ = 19.54 corresponding to polystyrene and at 2θ = 32.5, 38.5, 52.1, and 58.97 corresponds to Ni(OH)2. The composite was tested as an adsorbent using the batch technique. The impact of solution pH, contact time, and absorbent dose on the adsorption processes were studied to optimize the operational parameters. Kinetic and equilibrium studies showed that the adsorption processes followed pseudo-first-order kinetic and Freundlich isotherm. Maximum adsorption capacities of 32.73 and 58.24 mg g -1 were achieved in case of MB and Fe (III), respectively. Thermodynamic studies showed that ΔG values for the adsorption processes ranged from -0.075 to -1.435 kJ mol -1 by changing temperature from 303K to 343 in case of MB; ΔG values ranged from -0.467 to -1.548 kJ mol -1 by changing temperature from 303K to 343 in case of Fe (III). Negative values ΔG revealed that the adsorption processes were spontaneous and feasible. Hence, nickel hydroxide/PS composites could be potentially used for treating wastewater from MB and Fe (III).
