“…In fact, the presence of these peaks in the XRD pattern of MCM-41-NH2 indicates the formation of cavities with a regular hexagonal structure during amino-functionalization (Kirik et al, 2014). Numerous studies have reported that the formation of these cavities in an adsorbent may play an important role in the adsorption process as these cavities lead to a considerable number of active sites for the adsorption of pollutant molecules (Khodadadi et al, 2019, Mohammed et al, 2020b, Alwared et al, 2021.…”

Antibiotic pollutants discharged from pharmaceutical industries are often present in the aquaticenvironment due to ineffective treatment of pharmaceutical wastewater and are hazardous tohuman and aquatic life. Therefore, effective treatment of antibiotic-containing wastewater is ofutmost importance in the field of environmental protection. This study aims to evaluate theadsorption performance of an amine-functionalized MCM–41 mesoporous silica nanoparticlessystem (MCM–41–NH2) as an adsorbent for the removal of ciprofloxacin (CIP) antibiotic fromaqueous solution. Surface and structural characteristics of MCM–41–NH2 were examined usingscanning electron microscopy, X-ray diffraction, Brunauer–Emmett–Teller analysis, Fouriertransform infrared spectroscopy, and point of zero charge analysis. In addition, thermal stabilitywas investigated by thermogravimetric analysis. Via the proposed treatment, 99.25% CIPremoval was achieved under the following conditions: pH = 7; MCM–41–NH2 dose = 0.8 g/L;CIP concentration = 10 mg/L; adsorption time = 120 min; and shaking speed = 200 rpm.Isotherm study showed that the experimental data fitted well with the Langmuir equation.Moreover, the maximum adsorption capacity of MCM–41–NH2 for CIP was 164.3 mg/g.Thermodynamic parameters showed that the adsorption process of CIP on MCM–41–NH2 wasendothermic and spontaneous. Additionally, the increase in solution temperature had a positiveimpact on the removal of CIP. The kinetic data obtained at different CIP concentrations (10, 25,50, and 100 mg/L) were consistent with the pseudo-second-order model. MCM–41–NH2 couldbe recycled eight times in the proposed adsorption process, with a slight loss in its adsorptioncapacity. Compared with other adsorbents, MCM–41–NH2 was more effective for CIP removal.

“…The FT-IR analysis was carried out at Tehran University using a Jasco 4100 device in the spectral range 400-5000 cm -1 and their results were plotted in Fig. (8), it can be noticed from this figure that the peaks for unloaded MA free and immobilized form are as follows, respectively: the bands around (3412.08, 3751.55) cm -1 and (3425.58, 3755.4) cm -1 are the indication of the existence of the -OH groups. While the bands around 2927.94 cm -1 and 2926.01cm -1 confirm the existent of C-H aldehyde stretch.…”

“…Additionally, some dyes are toxic, mutagenic, or carcinogenic. Different methods have been used for the removal of dyes from wastewater including sorption (8), coagulation and flocculation (25), advanced oxidations (31), biological treatment and nanofltration (33). Among them adsorption is a simple, versatile and feasible process (34;16).…”

This study was aimed to investigate the potential adsorptive behavior of mixed algae for decolorization of methylene blue dye from aqueous solution in the form of free and immobilized. Effects of initial pH value (3-9), biosorbent dosage (0.02-0.5)g/L, and initial concentration (10-50) mg/L for different contact time (0-180) min at 200 rpm shaking speed were investigated. In addition, experimental data were analyzed using adsorption (Langmuir and Freundlich) isotherms as well as kinetic models. The results demonstrated that the maximum decolorization percentage was 93% and 91% by free and immobilized algae, respectively for pH 6, 10 initial concentration, 0.3g/100mL algae dosage, and 90 min contact time. The results revealed that the Langmuir isotherm model was adequate for describing the dye removal process (R2= 0.99) for both forms. Results of pseudo-second order kinetic model revealed best fitting with the sorption data indicating that chemisorption process is the dominant mechanism controlling the dye removal. Furthermore, the characterization study performed using FT-IR and scanning electron micrograph techniques, revealed that the used algal biomass has good biosorption capabilities associated to active groups and surface structure and confirming that the immobilization was successful.

Lately, there has been an increase in dye manufacturing, resulting in increased environmental pollution. Recent studies show a wide availability of usage adsorbents, including banana peels, potatoes, algae, etc. Food and Drug Administration prohibited the use of Rhodamine B (RhB) for its toxicity and harmful effects. Therefore, this study presents a wide range of non-conventional low-cost alternative adsorbents to remove RhB dye from wastewater. It has been observed that the mechanism of the dye adsorption is focused on kinetics, isotherm, and thermodynamics models, which depend on the chemical nature of the materials and various physicochemical experimental conditions such as solution pH, initial dye concentration, adsorbent dosage, and temperature of the system. The kinetic data of adsorption of RhB dye usually follow the pseudo-first-order and pseudo-second-order kinetic models. Several studies revealed that Langmuir and Freundlich adsorption isotherm models are frequently used to evaluate the adsorption capacity of the adsorbents. Furthermore, thermodynamic examination showed that RhB adsorption was endothermic and unconstrained in nature. Thus, both photocatalytic degradation and adsorption methods offer good potential to remove RhB dye from industrial effluents. The work is in progress to evaluate the possibility of using other modified waste biomass for industrial pollution control.
