“…In addition, the results of other studies show that in most cases, maximum Cd removal occurred in the pH range of 4.0–7.0 (weak acidic and neutral), which is in accordance with the results of the present study 32 . Maximum Cd removal occurred in the studies of Bayramoglu et al in pH 6.0 31 , Alakhras in pH 5.0 33 , Dolgormaa et al in pH 5.0 34 and Shen et al in pH 6.0 32 .…”

“…Solution temperature affects the rate of adsorption 59 . According to Arrhenius, absorption rate usually elevates with increasing temperature and reduces with decreasing temperature 33 . Such observation could be attributed to the increase in the size of the pores on the adsorbent surface or the increase in effective collisions between the adsorptive and the adsorbent 60 .…”

The adsorption of cadmium ions by magnetite (Fe3O4)@biosilica/alginate (MBA nano-hybrid) was the main aim of the present investigation. Herein, MBA nano-hybrid was synthesized via chemical precipitation technique. As-synthesized MBA nano-hybrid was characterized using FT-IR, FESEM and XRD analyzes. Based on the results, the maximum adsorption capacity of the adsorbent for the removal of Cd(II) was obtained at the initial pH of 7.0. At the initial Cd(II) concentration of 40 mg/L, increasing the reaction time to 180 min led to the Cd adsorption of 35.36 mg/g. Since the removal of Cd(II) after the reaction time of 60 min was insignificant, the reaction time of 60 min was considered as optimum reaction time for performing the experimental runs. According to the results, Langmuir isotherm and pseudo-second order kinetic models were the best fitted models with high correlation coefficients (R2 > 0.99). The results of thermodynamic study indicated exothermic (positive ΔH°) and spontaneous nature (negative ΔG°) of the adsorption of Cd(II) on the surface of MBA nano-hybrid. Negligible reduction in the adsorption capacity of the nano-hybrid was observed (16.57%) after fifth experimental runs, indicating high reusability potential of the as-synthesized nano-hybrid adsorbent.

“…These organic wastes show a terrible problem in water, even in low concentration, as their recalcitrance chemistry reduces sunlight penetration in deep water, causing difficulty in the biological work in this environment. [30][31][32] In addition, the COVID-19 pandemic causes much other waste provided by human biosafety security against the virus. However, the foundry industry supplies one of the most environmentally degraded wastes.…”

The proliferation of different pollutants in waters caused by anthropogenic and industrial activities has become a significant global concern, as they cause many problems, like severe health and environmental harm. Searching for green materials for water removal entirely and efficiently in this context is challenging. In this sense, innovative materials based on industrial waste become an incredible alternative, as they are waste, disposable incorrect in the environment, low-cost, and need to be adequately discharged. Many innovative materials based on industrial waste were performed in the literature, as these eco-friendly alternatives have great potential for many applications, including wastewater treatment. This overview presents various research that demonstrated different innovative materials based on industrial waste, their physicochemical properties, different properties, the adsorption removal, and other wastewater treatment reported based on different models. Based on the literature, we have also demonstrated that innovative materials based on industrial waste exhibit an incredible potential for the adsorption of various pollutants in water, indicating their promising solution of low-cost adsorption removal for wastewater treatment. Finally, this overview shows that these sustainable materials present significant potential for use in wastewater treatment.

“…Chitosan-based materials are widely used as bioadsorbents for wastewater treatment to remove heavy metals, and dyes exist at low concentrations. 3,[19][20][21][22] A recent review article by Saheed et al, 23 concluded that the modification of chitosan via different physical and chemical methods is a promising approach for the efficient removal of organic and inorganic pollutants from aqueous matrixes. Zalloum et al 24 have modified chitosan using Schiff base derivatives and used it to study the uptake of Cu (II) ions in a batch adsorption experiment.…”

Chemical modification of chitosan was successfully carried out using three derivatives namely: 3 hydroxybenzaldehyde, 2,3-dihydroxybenzaldehyde, and 3,5-di-tert-butyl-2-hydroxybenzaldehyde by a condensation reaction. Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), Brunauer–Emmett–Teller (BET) surface area, thermal gravimetric analysis (TGA), and X-ray diffraction (XRD) methods were performed for characterization of the chitosan-derived Schiff base adsorbent materials. The efficiency of the prepared adsorbents in removing cobalt and nickel ions from aqueous solution was explored, and experimental data were analyzed using isothermal and kinetic models. The BET surface area of chemically modified chitosan was greatly enhanced 125.83 m2 g-1 with mesoporous characteristics. The maximum uptake was recorded at pH 5-6, while the maximum removal capacity was 243.90 mg g-1 for cobalt ions whereas 166.67 mg g 1 was achieved for nickel ions. The kinetic data were better fitted using pseudo-second-order.
