“…This indicates that the biosorption of MB does not follow PFO kinetics. Several authors have reported that adsorption of MB on different adsorbents does not fit the PFO kinetic model (Sivalingam et al 2019;Siddiqui et al 2018).…”

“…7b). Sivalingam et al (2019) reported that the rate of adsorption of MB on different adsorbents followed PSO kinetics and rate constant values were determined as 0.0035, 0.0010 and 0.0089 g mg −1 min −1 for coal fly ash (CFA), nanozeolite (nFAZX) and commercial zeolite (CZX), respectively. Danish et al (2018) were reported that the adsorption of MB on activated carbon derived from banana trunk (BTAC) followed PSO model kinetic and the rate constant k 2 was found as 0.056 min −1 .…”

“…Many researchers have investigated to utilize cheap adsorbents to remove MB dye from wastewater. Some biological materials such as agricultural waste, some plants, fruit peels, even fungi and algae were used as cheap and effective adsorbents and called as biosorbents (Subramaniam and Ponnusamy 2015;Adegoke and Bello 2015;Sivalingam et al 2019;Danish et al 2018). Moghazy et al (2019) investigated that micro-grinded dried biomass of two macro-algal species as complementary biosorbent materials for MB removal from wastewater.…”

The use of lichens is insufficient in industry. To the best of our knowledge, there is no study on the use of lichens in the removal of dyes from aqueous media. The aim of this study is to draw attention to the biosorption capabilities of lichens which are natural, renewable and inexpensive sources, and to investigate the usability of nonliving lichen Pseudevernia furfuracea (L.) Zopf. (LPF) in methylene blue (MB) dye removal from aqueous solution. With the green chemistry approach, no chemical treatment was applied to the LPF and it was used as a natural biosorbent for the biosorption. The LPF samples were prepared and characterized and performed batch mode biosorption experiments studying the effect of various parameters on MB biosorption. The experimental data were fitted with four different kinetic models (pseudo-first order, pseudo-second order, Elovich model and intra-particle diffusion) which were evaluated for their validity. Identification of the biosorption mechanism of MB onto the LPF was performed by isotherm studies via three isotherm models [Langmuir, Freundlich and Dubinin-Radushkevich (D-R)], and the parameters of each model were determined. It was concluded that the biosorption rate and yield were high, the type of biosorption of MB onto the LPF was defined as chemical biosorption, and the surface of the LPF was decided energetically heterogeneous. The results indicate that the LPF biomass can be attractive options for MB dye removal from aqueous media.

Methylene blue (MB) is a cationic dye widely used in medicine as an antiseptic, also in other fields such as biology, chemistry, textile industry…etc. This pollutant exists in nature as the result of the fluid which is released from industries that can directly affect both the living organisms and the environment. This study consists of eliminating methylene blue by Fenton process under the influence of three parameters (pH,[FeII] and ratio R). The degradation of this substance was followed by a modeling of this process using statgraphics‐plus software. The best result was obtained by the central composite design (CCD) 2*3+star on three‐level ( low, medium, high) of which coefficient of correlation R2 equal to 0.96, and the optimal conditions found are pH= 2.9, R=23.6 and [FeII]=1.5.10−4 M, with a yield of elimination of MB of 100% after a 30 min of treatment. This optimization minimizes the number of experiments and the time of research.
