“…This phenomenon may be attributed to the removal of protein by the alkali and exposure of chitin/chitosan. Gallagher et al (1997) observed that methods such as autoclaving, calcium saturation and exposure to NaOH enhanced the biosorption capacity of Rhizopus oryzae from 7% to 15%. Uzun (2006) reported that chitosan is an excellent adsorber of RB5 dye.…”

“…This result was in agreement with the result reported by Fu and Viraraghavan [29] where the biosorption capacities of live, autoclaved, alkali-pretreated, acid-pretreated, and NaHCO3 pretreated biomass of Aspergillus niger to remove Congo red were 12.1, 13.47, 11.17, 14.39, and 14.72 mg/g, respectively. This may be due to the generation of anionic sites on the surface of fungal biomass [30].…”

Experimental and Isothermal Studies on Sorption of Congo Red by Modified Mycelial Biomass of Woodrotting FungusBatch biosorption experiments were carried out for the removal of Congo red from aqueous solution using native and pretreated mycelial pellets/biomass of Trametes versicolor. The effect of process parameters such as contact time, dye concentration, and pH on the extent of Congo red biosorption has been investigated. Higher dye concentrations resulted in lower biosorption. Increases in biomass dosage led to increases in the levels of biosorption. Biosorption kinetics and equilibrium data are essential basic requirements to develop an effective and accurate design model for the removal of the dye. A kinetic study showed that the biosorption of the dye on fungal biomass was a gradual process. Pseudo-first-order, pseudo-second-order, and Bangham's model were used to fit the experimental data. The results of the kinetic studies showed that the second-order kinetic model fitted well for the present experimental data. Equilibrium isotherms were analyzed by Langmuir, Freundlich, Dubnin-Radushkevich, and Temkin isotherms. The biosorption equilibrium data obeyed the Langmuir and Temkin isotherms well. Acidic pH was favorable for the biosorption of the dye. Studies on the pH effect and desorption show that chemisorption seems to play a major role in the biosorption process. Among the native and pretreated biomass studied, autoclaved biomass showed a better biosorption capacity.

“…In biosorption process, dye molecule is adsorbed onto the biomass through physical or chemical adsorption and thus avoids the formation of degraded dye products which may be more harmful than the dye itself. Biosorption via "renewable biomass" is a key advantage over nonrenewable adsorbents such as clay, peat, zeolite, lignite, and some forms of activated carbons [7].…”

One of the major contaminants of water bodies is dye pollutants that come from textile, paper, and leather industries. In this study, Casuarina equisetifolia needle (CEN) is used to remove methyl violet 2B (MV) from aqueous solutions. Batch experiments were done to investigate the contact time, effect of pH, initial dye concentrations, and temperature. Langmuir and Freundlich isotherm models were used to describe the interaction between the adsorbate and adsorbent. The sorption mechanism was described using Lagergren 1st order, pseudo 2nd order, and Weber-Morris intraparticle diffusion models. FTIR spectroscopy was used to analyze the functional groups of CEN before and after sorption with MV. Optimal conditions were found to be at room temperature with 2 h contact time and no pH adjustment was needed. Experimental data was best fitted onto Langmuir model with maximum adsorption capacity of 164.99 mg/g, while pseudo 2nd order best described the experimental data for the kinetics study. Thermodynamic parameters such as change in Gibbs free energy (Δ 0 ), enthalpy (Δ 0 ), and entropy (Δ 0 ) were also investigated.
