“…In these industries, large amounts of chemicals as well as organic dyes are used during the production process. The effluents of these industries are different from each other in terms of chemical quality and quantity and are one of the biggest sources of pollution (1)(2)(3). These effluents cause more water pollution and are measured based on the amount of suspended solids, heavy metals, acid, alkali, biological oxygen demand (BOD), and chemical oxygen demand (COD).…”

“…The effluents of these industries are different from each other in terms of chemical quality and quantity and are one of the biggest sources of pollution. [1][2][3] These effluents cause more water pollution and are measured based on the amount of suspended solids, heavy metals, acid, alkali, biological oxygen demand (BOD), and chemical oxygen demand (COD). Most of these chemicals and dyes can make primary contamination and also can be converted to dangerous secondary compounds that are toxic and carcinogenic through chemical processes.…”

Disposal of textile industrial effluents causes many environmental problems. The presence of chemical dyes in textile wastewater lead to the primary environmental pollution as well as the production of hazardous secondary compounds that are toxic and carcinogenic. In this study, Chitosan and Chitosan-zinc oxide (ZnO) nanocomposite were prepared and selected as a low-cost adsorbent with high adsorption capacity for removing reactive red 198 (RR 198) dye from contaminated. After preparation, it was characterized using Fourier-transform infrared spectroscopy [FT-IR], X-ray diffraction spectrophotometer [XRD], and scanning electron microscopy [SEM]. The effect of pH, temperature, time, adsorbent amount, and initial dye concentration were investigated in the removal efficiency of reactive red 198 (RR 198) dyes. The results showed that the maximum adsorption capacity (qm) obtained from the Langmuir equation was 172.41 mg/g in adsorbent dose of 0.1 g/L, pH: 4, temperature of 25 °C, adsorption time of 40 min. The thermodynamic parameters demonstrated the spontaneous and endothermic nature of the adsorption process. Due to the high efficiency of chitosan/ZnO nanocomposite in removal of RR 198 from water and advantages such as high adsorption capacity, simple synthesis, and easy application, it can be used as an effective method in removal of RR 198 from water.

“…44 Desorption by acetic acid was superior to the mixture (alcohol: acetic acid), probably due to the physical and chemical properties of OFX, which was soluble in acetic acid and able to desorb from FMBC into the acetic acid solution, and then gradually decreased adsorption may be due to the residual OFX on the surface of the biochar, thus occupying part of the active site and inhibiting the reactivation. 71 Aer ve cycles, the three methods were still able to reach 89.31% (130.84 mg g −1 ), 86.24% (126.34 mg g −1 ) and 75.78% (111.02 mg g −1 ) of the adsorption capacity before recycling, respectively. In addition, FMBC showed a high sorption capability of Rhodamine B (137.67 mg g −1 ) even aer 5 cycles in OFX removal, it was higher than the nanosorbent material prepared by Shaswat.…”

“…We investigated the effective parameters on the adsorption process, including solution pH (3, 5, 6, 9, and 11) that adjusted with 0.1 M HCl or NaOH with a pH meter (HANNA 211), adsorbent dosage (60, 80, 100, 120, and 150 mg L −1 ), initial antibiotic concentration (5,10,15,20, and 30 mg L −1 ), contact time (20,40,60,90, and 120 min), and temperature of the solution (298, 303, 308, 313, and 318 K). The removal ef ciency of TC was calculated using Equation 1 [52]. The adsorption capacity at equilibrium (q e ) and amount of soption at time t (q t ) were calculated using Equations.…”

This study aimed to synthesize Fe 3 O 4 @Methylcellulose/3-Aminopropyltrimethoxysilane (Fe 3 O 4 @MC/APTMS) as a new magnetic nano-biocomposite by a facile, fast, and new microwave-assisted method and to be utilized as an adsorbent for tetracycline (TC) removal from aqueous solutions. Fe 3 O 4 @MC/APTMS was characterized by Fourier transform-infrared (FTIR), Field emission scanning electron microscopy (FESEM), Energy dispersive spectroscopy (EDS), Mapping, X-ray diffraction (XRD), Thermal gravimetric analysis (TGA), Brunauer-Emmett-Teller (BET) and vibrating sample magnetometer (VSM). The point of zero charge (pH zpc ) value of the nano-biocomposite was estimated to be 6.8 by the solid addition method.Optimum conditions were obtained in TC concentration: 10 mg L −1 , adsorbent dosage: 80 mg L −1 , contact time: 90 min, and solution pH: 6 with the maximum TC removal of 90% and 65.41% in synthetic and actual samples, respectively. The kinetic and isotherm equations pointed to a pseudosecond order kinetic and Langmuir isotherm optimum tting models. Based on the values of entropy changes (ΔS) (50.04 J/mol k), the enthalpy changes (ΔH) (9.26 kJ/mol), and the negative Gibbs free energy changes (ΔG), the adsorption process was endothermic, random, and spontaneous.The synthesized adsorbent exhibited outstanding properties, including proper removal e ciency of TC, excellent reusability, and simple separation from aqueous media by a magnet. Consequently, it is highly desirable that Fe 3 O 4 @MC/APTMS magnetic nano-biocomposite could be used as a promising adsorbent for TC adsorption from aqueous solutions. HighlightsFe 3 O 4 @MC/APTMSas a new magnetic nano-biocomposite has been synthesized by a new microwave-assisted method and characterized with FESEM, EDS, Mapping, FT-IR, XRD, TGA, BET, and VSM techniques.The maximum removal e ciencies under optimal conditions (pH=6, TC concentration 10 mg L -1 , adsorbent dosage: 80 mg L -1 and contact time: 90 min) for synthetic and actual samples were obtained 90% and 65.41%, respectively.Isotherm, kinetic and thermodynamic study of tetracycline adsorption were investigated.Fe 3 O 4 @MC/APTMS exhibited excellentreusability property up to 5 cycles.
