“…Coefficients of determination (R 2 ) related to the Langmuir model applied to TT and MB biosorption data (R 2 = 0.965 for TT; R 2 = 0.990 for MB) were higher than those for the Freundlich model (R 2 = 0.955 for TT; R 2 = 0.938 for MB). In addition, the biosorption of methylene blue and thioflavin T by agricultural by-products from the hop (Humulus lupulus L.) [27] and methylene blue by water hyacinth biomass [31], agro-waste oil tea shell [13], Anethum graveolens biomass [32] and Tremella fuciformis biomass [33] was very well fitted by Langmuir model.

Abstract:In this work the biosorption of cationic dyes thioflavin T (TT) and methylene blue (MB) from single and binary solutions on dried biomass of freshwater moss Vesicularia dubyana as a function of contact time, pH, and biomass or sorbate concentration has been investigated. The prediction of maximum sorption capacities using adsorption isotherm models were also realized. Biosorption of TT and MB is a rapid process strongly affected by solution pH. Maximum sorption capacities Q max calculated from Langmuir isotherm were 119 ± 11 mg/g for TT and 229 ± 9 mg/g for MB. In binary mixture, the presence of MB caused significant decrease of TT sorption, advocating the competitive sorption between TT and MB. Results revealed that V. dubyana biomass exhibited significantly higher affinity to thiazine dye MB in comparison with benzothiazole dye TT from both single and binary solutions. Based on the obtained results, the competitive effects in binary system can substantially influence the sorption process and should be thoroughly evaluated before application of selected adsorbents for removal of basic dyes from colored effluents.

“…The spectrum of the dye‐loaded biomass showed slight shifting of peaks from their natural position with an alteration in intensity, indicating the involvement of surface functional groups present on AP‐Iva in the sorption of dye. The new band observed at 1330 cm −1 (C‐N stretching in amine groups) is characteristic of biosorption of MV on the biomass …”

“…Experiments were performed in a batch reactor (IKA, KS 130, 100 mL). The reaction was carried out at 25 °C under a desired agitation speed . The effects of the agitation speed (100–400 rpm), initial pH (3–10), dyes concentration (10–200 mg L −1 ), and biosorbent dose (0.1–3 g L −1 ) on the MV sorption rate were examined.…”

where k 1 (min −1 ) is the rate constant of pseudo‐first‐order model.…”

Removal of methyl violet dye by a low‐cost waste (Ajuga Pseudo‐Iva): Kinetic and equilibrium isotherm study

et al. 2018

In this work we describe the utilization of a low cost environmental biomass derived from Ajuga Pseudo‐Iva waste (AP‐Iva) for the purpose of dye removal from contaminated wastewater. The biosorbent was characterized by SEM, ATG‐DSC, and FTIR‐ATR techniques. The material's performance was studied by varying operating parameters such as initial dye concentration, pH, adsorbent dose, particle size, and contact time. The results obtained showed that MV dye was sorbed quickly enough for the first few minutes and achieved a good efficiency (∼80 %) after 30 min of reaction time. The kinetic data obtained at different concentrations were analyzed using pseudo‐first order, pseudo‐second order, Elovich, and intra‐particle diffusion models. The equilibrium sorption data were analyzed using Freundlich, Langmuir, Toth, Sips, and Temkin isotherms. The experimental data were correctly fitted to Toth and Sips isotherms.

BACKGROUND: This study investigates the adsorption of methylene blue (MB) and malachite green (MG) onto a novel biosorbent. Rapid industrialization pollutes water resources, causing serious environmental problems. Physical and chemical treatments were performed for biosorbent modification.RESULTS: In the present work, nano (n)TiO 2 was inserted into chitosan (Cts)-epichlorohydrin (ECH)-plum kernel shell (PKS) and the final product was characterized by various modern techniques such as Fourier transform infrared, X-ray diffraction, scanning and transmission electron microscopy and thermogravimetric analysis. Under optimized conditions, the maximum adsorption capacities of MB and MG by Cht/PKS/nTiO 2 -ECH (termed nTiO 2 -Composite) determined by the Langmuir model were 86.96 and 108.70 mg g −1 , respectively. Thermodynamic parameters such as ΔG°, ΔH°, ΔS°and E a were calculated, confirming the interaction of dyes with nTiO 2 -Composite as exothermic and spontaneous.CONCLUSIONS: This study shows that the newly synthesized nTiO 2 -Composite has a very high performance in dye removal.
