“…The adsorption of dye on a granular (Hadi et al, 2010 ) and a lignocellulosic waste biomass (Nethaji & Sivasamy, 2011 ) activated carbons has been measured, ranging between 400–450 and 2.4–4.0 mg dye/g adsorbent, respectively. Experimental adsorption capacities of a compost (Kyzioł-Komosińska et al, 2011 ) 0.018–12.74 mg g −1 , of peat (Sepúlveda et al, 2004 ) 25 mg g −1 , of fly ash (Sun et al, 2010 ) 35 mg g −1 , and of bentonite (Pająk et al, 2019 ) 31.29 mg g −1 , have been determined. Values for the dye retention by mesoporous carbons have been reported as 270 (Galán et al, 2013 ) and 271.39–497.93 mg g −1 (Peng et al, 2014 ).…”

Dyes, considered as toxic and persistent pollutants, must be removed from organic wastes prior to their composting and application in sustainable agriculture. Azo dyes, capable of altering the physicochemical properties of soil, are difficult to expel by conventional wastewater treatments. C.I. Acid Black 1 (AB 1), a sulfonated azo dye, inhibits nitrification and ammonification in the soil, lessens the nitrogen use efficacy in crop production and passes substantially unaltered through an activated sludge process. The retention of C.I. Acid Black 1 by raw and expanded perlite was investigated in order to examine the potential effectiveness of this aluminosilicate material toward organic waste cleanup. Dye adsorption proved spontaneous and endothermic in nature, increasing with temperature for both perlites. Expanded perlite having a more open structure exhibited a better performance compared to the raw material. Several of the most widely recognized two-parameter theoretical models, i.e., Langmuir, Freundlich, Temkin, Brunauer–Emmett–Teller (BET), Harkins–Jura, Halsey, Henderson, and Smith, were applied to reveal physicochemical features characterizing the adsorption. The Langmuir, Freundlich, Temkin, BET, Henderson, and Smith equations best fitted experimental data indicating that the adsorption of anionic dye on perlites is controlled by their surface, i.e., non-uniformity in structure and charge. This heterogeneity of surface is considered responsible for promoting specific dye adsorption areas creating dye “islands” with local dye supersaturations.

“…Intraparticle diffusion (IPD) models were used to investigate the rate limiting mechanism of HSsorption on bentonite. While the sorption kinetics in these experiments are complicated because of various consecutive processes, e.g., film/external diffusion, intraparticle diffusion, surface interaction by physisorption or chemisorption (Can, 2015;Nguyen et al, 2017;Sahoo and Prelot, 2020;González-lópez et al, 2022), these simplified kinetic models are commonly used to initially understand sorption processes in various contextsincluding bentonite sorption studies (Galambos et al, 201 ;Gomdje et al, 201 ;Dada et al, 2019;Pająk et al, 2019). Figure 3 and Table 2 presents the key results from comparing the non-linear plots of the applied kinetic models, as many recent studies recommend non-linear methods provide improved insight and reduced method bias than linearized methods (Zafar et al, 2015;Simonin, 2016;Nguyen et al, 2017;Moussout et al, 2018;Bujdák, 2020;Revellame et al, 2020;González-lópez et al, 2022).…”

The present research evaluates the influence of modification of smectite clay (BC) on its adsorption capacity of anionic dyes from aqueous solutions. Thermal (BC 250), acidic (BC H2SO4), and alkaline (BC NaOH) modification of clay was carried out. The clays were characterized by X-ray powder diffraction, energy-dispersive X-ray spectroscopy, and Fourier transform infrared spectroscopy. Adsorption of dyes was investigated by batch experiments at room temperature (23 ± 2 °C), a wide range of initial dye concentrations (1–1000 mg/dm3), and an adsorbent dose of 50 g. All modifications increased the clay’s adsorption capacity for Reactive Red 198, in the order BC H2SO4 > BC NaOH > BC 250 > BC; it was 10.32, 5.06, 3.32, and 2.92 mg/g, respectively. Acid and thermal modification of the clay increased its adsorption capacity for Acid Red 18, in the series BC H2SO4 > BC 250 > BC > BC NaOH; it was 3.07, 2.66, 2.16, and 1.28 mg/g, respectively. The experimental data were analyzed by Freundlich, Langmuir, Dubinin–Radushkevich, and Sips isotherms, using nonlinear regression. The experimental data best fitted the Sips isotherm. Taking into account the structure of the adsorbent and adsorbates and the results obtained, it can be concluded that the dyes were probably bound through chemisorption, by forming hydrogen bonds between Si–OH and Al–OH groups in the clay and –NH, –NH2, and –OH groups in the dyes. From the results obtained, it can be concluded that smectite clay is a promising material for dye adsorption.
