“…The magnitude of activation energy showed a type of adsorption that was physical or chemical. Achieving activation energy of 5-40 kJ/mol coincides with physisorption mechanism, while achieving activation energy of 40-800 kJ/mol coincides with chemisorption mechanism (32). The activation energy (E a ) in this study was 82.5497 kJ/mol, which is associated with chemisorption and has a higher potential.…”

“…Many researchers have reported the application of different nanosized adsorbents such as nanoparticles (NPs) and nanotubes (14). Recently, the preparation of magnetic nanoparticles (MNPs) has received a lot of attention because of its various technological applications in water purification, photocatalysis and other separation processes (such as extraction bioseparation (15)(16)(17), and separation of different ions (17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32). The MNPs are effective adsorbents due to their large specific surface area, low toxicity, and superparamagnetic behavior.…”

In this study, the magnetic 3-(trimethoxysilyl) propyl methacrylate (TMSPMA) – poly (4-vinylpyridine) (P4VP) was synthesized and characterized. Removal of Molybdenum (Mo) from aqueous solutions using prepared material as nanosorbent was investigated. The magnetic P4VP was prepared by copolymerization of P4VP with TMSPMA. The prepared adsorbent was characterized by various techniques including the X-ray powder diffraction (XRD), scanning electron microscopy (SEM), and Fourier-transform infrared spectroscopy (FTIR). The batch adsorption technique was applied and the effect of several important parameters such as pH of the aqueous solution, adsorbent dose, initial Mo(VI) concentration, contact time, and temperature was evaluated. Desorption behavior of Mo(VI) and the effect of foreign ions (Cd2+, Ca2+, Co2+, Fe3+, Ba2+ and Pt4+) in real samples were also investigated. Co (II) and Pt (IV) had a greater impact on the adsorption process than other foreign ions. The maximum capacity for Mo(VI) adsorption on the prepared adsorbent was 4.87 mg/g, which was obtained at a temperature of 40°C with an initial concentration of 10 mg/L of Mo(VI). The adsorption isotherms were best fitted with the Weber Van Vliet isotherm model. The kinetic data were fitted well with the pseudo-second-order equation with a high correlation coefficient (R2 > 0.99). Based on the negative standard Gibbs free energy change (ΔG° < 0) and the positive standard enthalpy change (ΔH° > 0), it was found that the adsorption was an endothermic and a spontaneous process in nature.

Forward osmosis (FO) is considered among the most encouraging water desalination processes as a result of its high performance and low energy demand. Thin‐film composite (TFC) hollow fibers (HF) were synthesized and examined in the FO process. Three different concentrations of polyvinyl chloride (PVC) support polymer were fabricated via the phase inversion technique. The polyamide layer was synthesized on the outer surface of the PVC‐HF substrate via interfacial polymerization (IP) reaction. To the best of our knowledge, PVC HF was used in this research for the first time as a support for TFC‐FO membranes. PVC HFs have high‐quality specifications that are expected to have outstanding performance in TFC‐FO applications, especially for water desalination. The obtained membranes were characterized using contact angle measurement, scanning electron microscopy, atomic force microscope and Fourier‐transform Infrared. The performance of the PVC‐TFC HF was examined in the FO under standard conditions. Results showed that the membrane fabricated with a lower concentration of PVC substrate exhibited higher water flux in comparison to the higher concentration PVC membrane. Changing the concentration of PVC from 15% to 18% reduced water flux from 25 to 13 L m−2 h−1; however, salt flux also decreased from 8 to 3 g m−2 h−1.

“…Mining, jewelry, Cd-Ni battery, alloy, metallurgical, and metal plating industries are stated to be the major source of metal-containing waste pollution [5,6]. Nickel concentrations in air are typically 0.00001-0.003 µg/ m 3 in remote places, 0.003-0.03 µg/m 3 in municipal and metropolitan places, and 0.07-0.77 µg/m 3 in nickel processing industries as well as in similar manufacturing plants [7]. According to the World Health Organization (WHO, the year 2020), the nickel concentration in drinking water is 2-13 μg/L in European countries.…”

Sawdust is a waste material, which is generally produced during making furniture and other necessary wood products. With a view to utilizing this waste material, a biosorbent was prepared from mahogany (Swietenia macrophylla) sawdust through simple chemical treatment and was used to remove nickel ion (Ni2+) from an aqueous solution. The adsorbent material was characterized by Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), and energy dispersive X-ray (EDX) analysis. The effects of biosorbent dosage (2∼18 g/L), pH of the tested solution (4∼10.5), contact time (up to 360 min), and temperature (298∼318 K) were studied in batchwise experiments. The maximum adsorption capacity of the treated sawdust was determined to be 13.42 mg/g at an optimum condition (sorbent dose of 15 g/L, pH of 9, and temperature of 298 K). The experimental data extrapolation revealed that the adsorption process fitted the Langmuir isotherm model and the kinetics was a pseudo-second-order kinetic model. The obtained thermodynamic parameters indicated that the adsorption reaction was spontaneous, endothermic, and random in nature. The study revealed that sawdust biosorbent has potential adsorption efficiency for nickel ion removal from an aqueous solution.
