“…XPS survey scan of 5% Mn 3 O 4 -Bi 2 O 3 is provided in Figure 1B, wherein the peaks related to splitted and core levels of componets of the composite, i.e., Bi4f, Bi4d, Bi4p, Mn2p, O1s are observable. The presence of all peaks at binding energy values are in agreement with literature values [ (Li et al, 2014;Hameed et al, 2015;Sood et al, 2015;Astuti et al, 2016;Qamar et al, 2017a;Qamar et al, 2017b;Alhogbi et al, 2020;Mahmoud and Mahmoud, 2021;Kasbaji et al, 2022)].…”

“…The flask having a heterogeneous mixture of adsorbate and adsorbent were shaken in an orbital mechanical shaker at 250 rpm, 28 ᵒC, 7 pH for 5 h. The adsorption of MB on each adsorbent was monitored by collecting samples from each flask after 30, 60, 120, 180, 240, and 300 min (contact time) shaking time. The filtered samples were measured for percent adsorption and adsorption capacity (q t ) using the following equations in a UV-Visible spectrophotometer after being filtered with a syringe filter [ (Mahmoud and Mahmoud, 2021;Kasbaji et al, 2022)]: Where C o is the initial concentration of the adsorbate; C t is the concentration of the adsorbate at any time (t); V is the volume of adsorbate in (l) and W is the amount of adsorbent in grams (g). The MB concentration was calculated using UV-Visible spectrophotometer at 665 nm (λ max ).…”

Metal oxide-based adsorbents are quite in for wastewater treatment because of their selectivity, stable structure and very low solubility in aqueous systems. To explore the adsorption of methylene blue (MB), Mn3O4-Bi2O3 adsorbents were made using a wet-impregnation technique with various concentrations of Mn3O4. The presence of Mn3O4 contents on the surface of monoclinic Bi2O3 was confirmed through representative scanning electron micrographs. The diffractions pertaining to cubic Mn3O4 and monoclinic Bi2O3 were noticed in the XRD pattern of 5% Mn3O4-Bi2O3 which confirm the composite nature of the adsorbent. XPS analysis revealed the existance of Bi 4f, Bi 4d, Bi 4p, Bi4s, and Mn 2p core levels in Mn3O4-Bi2O3. The adsorption study divulged highest efficiency (∼95% and qe = ∼1.4 mgg-1) of 5% Mn3O4-Bi2O3 composite among other contestants in removing 30 ppm MB at 28 ° C, pH 7 and 250 rpm. In addition to the determination of adsorption ability, the effect of preliminary dye concentration (5, 10, 20, and 30 ppm) and contact time (0.5–6 h) on the removal efficiency of prepared adsorbents were also monitored. The adsorption data from the batch experiments were evaluated using the Langmuir, Freundlich, Temkin, and Dubinin-Radushkevich-Kaganer (DRK) adsorption isotherms and pseudo 1st and 2nd-order kinetic models. The fitting of adsorption isotherms and kinetic models revealed the formation of adsorbate’s monolayer on the surface of adsorbents through the process of chemisorption. Through FTIR measurement, the MB adsorption onto the effective adsorbent (5% Mn3O4-Bi2O3) was also confirmed. Moreover, TGA analysis showed ∼1.5% weight loss by 5% Mn3O4-Bi2O3 before MB adsorption whereas ∼2.6% weight loss was noticed after dye adsorption onto the adsorbent. The antifungal activity was evaluated against the fungi A. solani and M. fructicola using the agar well diffusion technique. The 5% Mn3O4-Bi2O3 composites have exceptional antifungal characteristics compared to Bi2O3 and Mn3O4, with zone inhibition values of 58.6 and 53.9 mm, respectively.

“…Among the most commonly used adsorbents are those of biological origin, such as Bio-based functionalized adsorptive polymers for sustainable water decontamination, 1 coffee grounds cellulose/ sodium alginate double-network hydrogel beads, 2 terrestrial and marine natural fibers 3 and the new alkali-modified bio-sorbents for cadmium removal from industrial discharges. 4 Calcium phosphates have garnered substantial attention for their efficacy in adsorbing various pollutants, including heavy metal ions, 5 nitrobenzene, 6 fluoride, 7 textile dye 8 and biologically significant macromolecules like amino acids 9 and proteins 10 . Natural phosphate and poorly crystalline synthetic hydroxyapatite have shown promise in removing dyes from aqueous solutions.…”

The present study was conducted to evaluate the feasibility of apatitic tricalcium phosphate with a Ca/P ratio of 1.50 for the adsorption of phenol and tyrosine from aqueous solutions. The adsorbent was synthesized at room temperature using an aqueous double decomposition method and characterized through physicochemical methods. Batch adsorption studies were conducted as a function of contact time, initial adsorbate concentration, temperature, and pH. The adsorption kinetics of phenol and tyrosine were well fitted to the pseudo-second-order model. The maximum adsorption capacity was found to be 5.56 mg/g for phenol and 9.65 for tyrosine mg/g at 298 K. The adsorption of phenol and tyrosine was well explained using the Langmuir, Freundlich, Temkin, and Dubinin-Radushkevick models. The Langmuir model is the most suitable, with a maximum monolayer adsorption capacity of 7.32 mg/g for phenol and 11.43 mg/g for tyrosine at 298 K. The thermodynamic parameters indicate that the adsorption process is favorable, spontaneous, exothermic, and controlled by physisorption with electrostatic interactions between compounds containing the phenolic group and apatite. The results of this study have demonstrated the potential utility of apatitic tricalcium phosphate, which could be developed into a viable technology for the adsorption of compounds containing the phenolic group from aqueous solutions.

“…In fact, global climate concerns and the exhaustion of fossil-based feedstocks for fuels and chemicals have driven the demand for viable alternatives to produce sustainable materials. [1][2][3][4][5] As the most accessible and recyclable carbon resource on Earth, lignocellulosic biomass is recognized as the key renewable material for an alternative and sustainable technology. [6][7][8] Increasingly, lignocellulosic materials are integrated into different technologies via several physicochemical conversions to produce a variety of sustainable and ecological materials in different fields.…”
