Assessment of the biosorption characteristics of a macro-fungus for the decolorization of Acid Red 44 (AR44) dye

Decolorization of dye Reactive Black 5 by newly isolated thermophilic microorganisms from geothermal sites in Galicia (Spain)

“…At acidic pH values, there is more interaction between the negatively charged dye molecules and positively charged binding sites on the biosorbent surface. This fact was also reported by Akar et al [42] and by Iqbal and Saeed [43] in studies on dye biosorption by the macro-fungus Agaricus bisporus and by the white-rot fungus Phanerochaete chrysosporium, respectively. Increasing sorption capacity with decreasing pH was also reported for algae, bacteria and yeasts [44][45][46].…”

Application of Spent Li-Ion Batteries Cathode in Methylene Blue Dye Discoloration

“…After 24 h, the MB concentration was monitored using a UV-spectrophotometer FEMTO Cirrus 80 PR at 659 nm. The MB dye adsorption capacity ( ) was determined by (8) [15], in which and are the initial and equilibrium MB concentration, respectively. For the determination of the surface area, the Langmuir isotherm (see (9)) was considered, in which max is the monolayer adsorption capacity (mg/g) and is a constant related to free energy of adsorption [15].…”

“…The MB dye adsorption capacity ( ) was determined by (8) [15], in which and are the initial and equilibrium MB concentration, respectively. For the determination of the surface area, the Langmuir isotherm (see (9)) was considered, in which max is the monolayer adsorption capacity (mg/g) and is a constant related to free energy of adsorption [15]. To convert max into surface area (m 2 /g), each MB molecule with 1,70 × 10 −18 m 2 [14] was considered.…”

Untreated clay with high adsorption capacity for effective removal of C.I. Acid Red 88 from aqueous solutions: Batch and dynamic flow mode studies

“…This process is not only economic and feasible but also produces high quality of water [7,8]. The dye adsorption potentials of many low-cost and natural materials have previously been reported upon, including Thuja orientalis [9], hazelnut shell [10], macro-fungus [11], baggase pith [12], Pyracantha coccinea [13], kidney bean [14], calcined alunite [15]. On the other hand some modification procedures were applied to improve the adsorption performances and characteristics of the adsorbent materials [16][17][18].…”
