“…About 0.5 ml of the solution in the Erlenmeyer flask was then separated from the adsorbent, and the concentration of MB dye was detected at different interval times and the equilibrium. The concentration of MB dye was determined by spectrophotometry at λ max 665 nm [38,59].…”

“…Industrial effluents, instigated by the production processes of the cosmetics, textiles, paper, leather, and paint industries, are known to have a significant quantity of toxic aromatic dyes, mostly the thiazine cationic dyes such as methylene blue (MB) [37][38][39][40]. Notwithstanding the valuable uses of MB (C 16 H 18 ClN 3 S) in various scientific domains, the dye has detrimental effects on humans and other living organisms as well as the environment owing to its water solubility tendency [41,42].…”

“…The colored effluents disposed of, released, or discharged during the production processes of the cosmetics, textiles, paper, leather, and paint industries into the ecosystem are one of the predominant causes of the ensuing environmental pollution as well as awkwardness in the water bodies (aquatic environment) in particular [24,29,43,44]. The MB is a characteristic industrial effluent, and it is one of the prevalent commercial thiazine and azo dyes [38,39,43,45].…”

The synthesized biochars derived from sawdust (SD) SD ozone (SDO) biochar, purified SD (PSD) biochar, and sonicated SD (SSD) biochar, which was employed in the confiscation of methylene blue (MB) dye ion, were characterized employing “Brunauer–Emmett–Teller (BET), scanning electron microscope (SEM), Fourier Transform Infrared (FTIR), and Thermal gravimetrical analysis (TGA).” The impact of various factors, such as pH, biochar dosage, and initial concentration, on MB dye sequestration, was tested in this study. It was found that the biosorption of MB dye to the various biochars was dependent on the solution pH, with optimum confiscation of MB observed at pH 12 for all biochars. Pseudo-second-order (PSO), Freundlich (FRH)- (SDO and SSD biochars), and Langmuir (LNR)- (PSD biochar) models were used to best describe the biosorption process of MB dye to various biochars. Based on the LNR model fitting to the experimental data, the optimum sorption capacities obtained using SDO, SSD, and PSD biochars were 200, 526, and 769 mg/g, respectively. Electrostatic interaction and hydrogen bonding played an important role in the interaction mechanism between the various biochars and MB dye. Hence, these studied SDO, PSD, and SSD biochars prepared from cheap, easily accessible, biodegradable, and non-hazardous agro-waste materials can be effectively used for the removal, treatment, and management of MB dye as well as other industrial effluents before their disposal into the environment.

“…For this reason, heavy metal-containing wastewater and sewage treatment are of great importance. Scientists have proposed different methods such as membrane separation, chemical precipitation, adsorption, biological treatment, redox, and ion exchange to remove heavy metal ions from wastewaters [16][17][18][19][20][21][22][23]. Among these techniques, the adsorption technique has been the preferred method since it eliminates some disadvantages such as high equipment cost, toxic sludge, and other waste production seen in other methods [24][25][26][27][28][29].…”

A new biochar was produced from pea peel residues by the dehydration process. The effect of the obtained new biochar on the ability to remove Cr6+ ions from the aqueous solution was investigated. Biochar-SO was obtained from pea peel by dehydration of biochar with 50% sulfuric acid. The obtained biochars were characterized by Fourier transform infrared (FT-IR); Brunauer, Emmett and Teller (BET); Barrett-Joyner-Halenda (BJH); thermogravimetric analysis (TGA); differential scanning calorimetry (DSC); scanning electron microscope (SEM); and energy-dispersive X-ray (EDAX) analyses. The optimum pH value for Cr6+ ion removal was determined as 1.48. The maximum removal percentage of Cr6+ ions was 90.74% for Biochar-SO of 100 mg·L−1 Cr6+ ions initial concentration and 1.0 g L−1 adsorbent dosage. The maximum adsorption capacity (Qm) of biochar-SO was 158.73 mg·g−1. The data obtained were analyzed with Langmuir, Freundlich, Temkin, and Dubinin-Radushkevich (D-R) isotherm models. In addition, the data obtained from these isotherm models were tested using different error functions (hybrid error function (HYBRID), average percent errors (APE), the sum of the absolute errors (EABS), chi-square error (X2), and Marquardt’s percent standard deviation (MPSD and the root mean square errors (RMS)) equations. It was the Freundlich isotherm model that best fits the experimental data of biochar-SO. Kinetic data were evaluated by pseudo–first-order (PFO), pseudo–second-order (PSO), Elovich, and intraparticle diffusion models. The adsorption rate was primarily controlled by the PSO rate model with a good correlation (R2 = 1). The adsorption mechanism of biochar-SO to remove Cr6+ ions can be based on electrostatic interaction and ion exchange with exchangeable cations in biochar such as aluminum, silicon, and calcium ions for chromium. The results indicate that biochar-SO is a promising adsorbent for the adsorption of Cr6+ ions that can be employed repeatedly without substantial loss of adsorption effectiveness.

Magnetic cellulose nanobiocomposites have been designed and synthesized from sugarcane bagasse to develop new and adequacy adsorbents for heavy metals adsorption from water. In this study, three different ways were followed for three nanocomposites' preparation: (1) coating Fe 3 O 4 through preparation of dissolved cellulose in (7% NaOH and 12% urea) aqueous solution (NFC1), (2) coating Fe 3 O 4 with cellulose through the co-precipitation (NFC2) and (3) crosslinking the cellulose and Fe 3 O 4 with formaldehyde (NFC3). The high-resolution transmission electron microscope (HR-TEM) images confirmed the particle size was ranged from 6 to 25 nm. The three novel nanocomposites' characterization was accomplished by study of surface area, Fourier transform infrared (FT-IR), thermal gravimetric analysis (TGA) and X-ray diffraction (XRD). The sorption feature of NFC1, NFC2 and NFC3 toward Cu(II), Cd(II) and Pb(II) ions was explored using the batch equilibrium technique with various experimental controlling parameters. The efficiency of NFC1 appears to be the best for removal of Pb(II) and Cu(II) (3150 and 2150 μmol g −1 ) and NFC2 more adequate nanocomposite for removal of Cd(II) 800 μmol g −1 . The optimum time was proceeded via fast sorption equilibrium at 5-30 min and better fitted with the pseudo-second order kinetic model. Adsorption isotherm obeys Langmuir isotherm that provides better model than the Freundlich isotherm model. According to the thermodynamic parameters, the adsorption was dominated by enthalpic rather than the entropic changes.
