“…As shown in Figure 3, the biosorption of the dye increased with increasing temperature up to 26ºC. The increase in biosorption could be due to increased surface activity and increased kinetic energy of the dye molecule (Aksu and Çağatay, 2006). The decrease in biosorption capacity of T. versicolor.…”

In this study, lyophilized Trametes versicolor biomass is used as a sorbent for biosorption of a textile dye, Sirius Blue K-CFN, from an aqueous solution. The batch sorption was studied with respect to dye concentration, adsorbent dose and equilibrium time. The effect of pH and temperature on dye uptake was also investigated and kinetic parameters were determined. Optimal initial pH (3.0), equilibrium time (2 hrs), initial dye concentration (100 mg l -1 ) and biomass concentration (1.2 mg l -1 ) were determined at 26ºC. The maximum biosorption capacity (qmax) of Sirius Blue K-CFN dye on lyophilized T. versicolor biomass is 62.62 mg/g. The kinetic and isotherm studies indicated that the biosorption process obeys to a pseudo-second order model and Langmuir isotherm model. In addition, the biosorption capacities of fungal biomass compared to other well known adsorbents such as activated carbon and Amberlite, fungal biomass biosorptions capacities were found to be more efficient.

“…These functional groups are important in the formation of London Vander Waals bonding since they play major roles in binding the metal ions to the adsorbents [21]. According to Aksu and Cagatay [22] who stated that lower sorbent dosages yield higher uptake but lower percentage removal efficiencies. This is applicable to this study which showed that higher percentage removal of metal ions at different dosages increased with increase in adsorbent dosage.…”

Abstract:The release of potentially toxic elements either by anthropogenic or industrial activities has deteriorated water quality rendering water bodies unsuitable. It was on this basis that readily available agricultural waste was used to treat simulated wastewater containing the potentially toxic element (Ni and Co). Adsorption studies of Co and Ni from aqueous solution were performed using spines of Bombax buonopozense (raw), carbon prepared from Bombax buonopozense (AC 1 ) and activated carbon prepared from modification of spines of cotton silk tree (AC 2 ). Batch adsorption techniques were carried out as a function of contact time, pH, initial concentration, temperature, and dosage. The respective optimum contact times required for adsorption Co and Ni were 90 min. Characterizations of adsorbents were carried out which include: bulk density, hardness, electrical conductivity, ash contents, percentage moisture, and yield. Fourier transform infra-red spectroscopy (FTIR) showed that functional groups in the sorbents were responsible for the adsorption process. The adsorption isotherms data were tested for Langmuir, Temkin and Freundlich equations. The pseudo-first-order, pseudo-second-order, Elovich and diffusion (intra-particle) models were investigated on the adsorption kinetic data. This could be as a result of ion exchange involved in the sequestration of metal ions by the adsorbents. Therefore, sorption using spines of Bombax buonopozense has been adjudged as one of the best tools for replacing conventional methods for the removal of these metals because of its efficiency, costeffectiveness and the availability of the adsorbents.

“…Among the fungal biomasses tested so far, C. elegans proved to be the most versatile with respect to this parameter: Kiran and collaborators [28], treating the dye Acid Red 57 with the biomass of Cephalosporium aphidicola, noting that q e decreased proportionally to 0 with the increase of initial pH between 1 and 6. Aksu and Çağatay [29], studying the Rhizopus arrhizus biomass for the removal of the dye Germano Turquise Blue-G, observed the maximum q e at pH 2 and total ineffectiveness at pH 4. Likewise, Khambhaty and collaborators [30] using Aspergillus wentii to remove Brilliant Blue G observed an evident and constant q e decrease when the solution was increased from pH 2 to 10.…”

Abstract:The biosorption potential of three fungal waste-biomasses (Acremonium strictum, Acremonium sp. and Penicillium sp.) from pharmaceutical companies was compared with that of a selected biomass (Cunninghamella elegans), already proven to be very effective in dye biosorption. Among the waste-biomasses, A. strictum was the most efficient (decolorization percentage up to 90% within 30 min) with regard to three simulated dye baths; nevertheless it was less active than C. elegans which was able to produce a quick and substantial decolorization of all the simulated dye baths (up to 97% within 30 min). The biomasses of A. strictum and C. elegans were then tested for the treatment of nine real exhausted dye baths. A. strictum was effective at acidic or neutral pH, whereas C. elegans confirmed its high efficiency and versatility towards exhausted dye baths characterised by different classes of dyes (acid, disperse, vat, reactive) and variation in pH and ionic strength. Finally, the effect of pH on the biosorption process was evaluated to provide a realistic estimation of the validity of the laboratory results in an industrial setting. The C. elegans biomass was highly effective from pH 3 to pH 11 (for amounts of adsorbed dye up to 1054 and 667 mg of dye g −1 biomass dry weight, respectively); thus, this biomass can be considered an excellent and exceptionally versatile biosorbent material.
