“…The pseudo-first-order kinetic model was expressed by the Equation (10) [ 73 ] as below:

where t (min) was the adsorption time; q e and q t (mg/g) were the adsorption capacities of the powders at equilibrium time and t time respectively; k 1 (min −1 ) was the adsorption rate constant of pseudo-first-order kinetic model. It was clear in Supplementary Materials Figure S4a and Table S8 that the linear correlation coefficients for the pseudo-first-order kinetic models were from 0.31 to 0.90 under different initial Cu 2+ ion concentration conditions, and the calculated q e,cal values were close to the experimental q e,exp values [ 77 ].…”

The treatment of wastewater containing heavy metals and the utilization of wool waste are very important for the sustainable development of textile mills. In this study, the wool keratin modified magnetite (Fe3O4) powders were fabricated by using wool waste via a co-precipitation technique for removal of Cu2+ ions from aqueous solutions. The morphology, chemical compositions, crystal structure, microstructure, magnetism properties, organic content, and specific surface area of as-fabricated powders were systematically characterized by various techniques including field emission scanning electron microscopy (FESEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), vibrating sample magnetometer (VSM), thermogravimetric (TG) analysis, and Brunauer–Emmett–Teller (BET) surface area analyzer. The effects of experimental parameters such as the volume of wool keratin hydrolysate, the dosage of powder, the initial Cu2+ ion concentration, and the pH value of solution on the adsorption capacity of Cu2+ ions by the powders were examined. The experimental results indicated that the Cu2+ ion adsorption performance of the wool keratin modified Fe3O4 powders exhibited much better than that of the chitosan modified ones with a maximum Cu2+ adsorption capacity of 27.4 mg/g under favorable conditions (0.05 g powders; 50 mL of 40 mg/L CuSO4; pH 5; temperature 293 K). The high adsorption capacity towards Cu2+ ions on the wool keratin modified Fe3O4 powders was primarily because of the strong surface complexation of –COOH and –NH2 functional groups of wool keratins with Cu2+ ions. The Cu2+ ion adsorption process on the wool keratin modified Fe3O4 powders followed the Temkin adsorption isotherm model and the intraparticle diffusion and pseudo-second-order adsorption kinetic models. After Cu2+ ion removal, the wool keratin modified Fe3O4 powders were easily separated using a magnet from aqueous solution and efficiently regenerated using 0.5 M ethylene diamine tetraacetic acid (EDTA)-H2SO4 eluting. The wool keratin modified Fe3O4 powders possessed good regenerative performance after five cycles. This study provided a feasible way to utilize waste wool textiles for preparing magnetic biomass-based adsorbents for the removal of heavy metal ions from aqueous solutions.

Eco-friendly nanocomposite (HS) was prepared from agriculture sources and characterized for remediation of wastewater from lead and cadmium ions. The nanocomposite was prepared from humic acid with silica (HS) which was prepared from compost and rice husk. The nanocomposite was characterized by FTIR, XRD, SEM, Zeta potential, BET and SEM-EDX. The removal of metal ions was studied using a variety of operating parameters, including pH, metal ion concentration, adsorbent dosage, and contact time. In both Pb 2+ and Cd 2+ , the best removal efficiency was found at pH 5.6 and 6. Pb 2+ and Cd 2+ had equilibrium times of 30 and 60 minutes, respectively. The adsorption process was exothermic and spontaneous in nature, according to thermodynamics. In terms of describing and evaluating the adsorption process, the Langmuir, Freundlich, and Temkin models are the most accurate, according to isotherm adsorption studies. Nanocomposite (HS) before and after adsorption was confirmed by EDX to involve lead and cadmium ions. The adsorption capacity of HS was 22.86 and 6.25 mg/g for Pb 2+ and Cd 2+ , respectively.

Aquaculture effluent treatment is essential to eliminate the undesirable characteristics of water to ensure cleaner production and environmental sustainability. In an effort to develop green coagulant without compromising cost, this research investigated the feasibility of aquaculture effluent (AQEF) pollutant removal using Picralima nitida seeds extract (PNSC) and its bio-coagulation/adsorption kinetic characteristics with the substrate in water. The coagulative decrease was observed in terms of TD (turbidity), TSS (total suspended solids), COD (chemical oxygen demand), BOD (biochemical oxygen demand), and COLR (color) from AQEF. The active coagulant was extracted from the seeds and analyzed for its spectral and morphological characteristics through FTIR and SEM. The influence of PNSC dosage (0.10–0.50 g L−1), pH (2–10), settling time (0–60 min), and temperature (303–323 K) on the removal of contaminants were surveyed. The process kinetics of coagulation–flocculation were also explored. Maximal TD reduction of 90.35%, COD (82.11%), BOD (82.38%); TSS (88.84%), and COLR (65.77%) at 0.2 g PNSC L−1, pH 4, and 303 K was achieved. Analysis of variance (ANOVA) tests proved that pH, temperature, and settling time had a significant effect on pollutant removal. Results fitted Von Smoluchowski’s perikinetics theory at the optimum conditions, which gave R2 > 0.900. At perikinetics circumstances, the Kb (reaction rate) and $${t}_{f\frac{1}{2}}$$ t f 1 2 (half-life) correspond to 0.0635 Lg−1 min−1 and 1.9 min. More so, sorption results fitted the Lagergren over the Ho model. Additionally, the net cost of using PNSC to handle 1 L of AQEF (including electricity, material, and labor costs) was evaluated to be €4.81. Overall, the PNSC appears reliable and useful in pretreating AQEF for improved biodegradability and superior effluent quality.
