“…If K a is large, even a short bed will avoid breakthrough, but as K a decreases, a progressively longer bed would be required to avoid breakthrough. In the present study, very small value of the rate constant K a in the BDST model indicated that a longer bed would be required to avoid breakthrough . The adsorption bed was exhausted after ∼3.1 h ( t b – t e ) after the breakthrough occurred, which indicated that the adsorption zone was almost saturated at the time of exhaustion.…”

Adsorption behavior of remazol reactive dyes from textile effluent was investigated using Rhizopus arrhizus as a biosorbent in up-flow fixed-bed micro column. The characteristics of mass transfer zone (MTZ), where adsorption in column occurs, were affected by bed depth and flow rate. The height of mass transfer zone (HMTZ), the rate of mass transfer zone (RMTZ), the effluent volume (V eff ) and the column capacity at exhaustion (q column ) were estimated for the removal of dyes by the biosorbent. Thomas and Yoon-Nelson models were applied to the experimental data to predict the "S" shaped breakthrough curves and to determine the biosorption capacity of the column. Both the models were found suitable for describing the whole dynamic behavior of the column with respect to flow rate and bed depth. Hutchins BDST model showed that the variation of the service time with the bed depth was highly linear, thus, indicating its validity when applied to the continuous microcolumn studies. The empty bed residence time model (EBRT) indicated that the biosorbent exhaustion rate decreased with increasing EBRT. The results of this study indicated the applicability of fixed-bed micro column for removing remazol reactive dyes from the textile effluent.

“…Methylene blue (MB), an organic cationic dye, has extensive applications including dying of cotton or wool or silk, leather dyeing, plastics coloring, paper coloring, manufacturing of paints and printing ink [2] and also in the treatment of fungal infection and determination of microbial load in milk [3]. MB causes various adverse effects on human health such as increased heart rate, vomiting, nausea, diarrhea, breathing difficulties (dyspnea), cyanosis, convulsions for inhalation, eye injury, fever, headache, dizziness, mental confusion, cancer and hypertension [4][5][6]. MB removal is difficult due to its complex atomic structure, xenobiotic properties, high light visibility, stability and oxidation reaction [4,7].…”

Removal of methylene blue (MB) dye from aqueous solution was studied using jute stick charcoal (JSC), prepared from jute (Corchorus olitorius) stick: an affordable and available agricultural by-product, as a low-cost adsorbent. All the experiments were carried out in batch mode. Controlling factors of the system, including contact time, solution pH, JSC dose and initial MB concentration, were investigated to study their effects on MB adsorption. JSC was characterized by Fourier transform infrared spectroscopy and field emission scanning electron microscope. Adsorption equilibrium data fitted well with Freundlich and Halsey adsorption isotherms that describe the multilayer adsorption on heterogeneous surface. The maximum adsorption capacity calculated by the Langmuir isotherm was 29.32 mg/g. The MB adsorption process was well described by the pseudo-second-order kinetic model, and the MB diffusion in JSC was the potential rate-controlling step. Finally, JSC is a promising adsorbent for the adsorption of MB from aqueous solution.

“…The solution pH is an important parameter influencing the overall charges and thus decides the sorption behavior of solute onto the surface of biosorbent [4,13]. In the present study, the effect of pH on biosorption of methylene blue by K. alvarezii was studied over a pH range of 5 -9.…”

In this work, non-living red seaweed (Kappaphycus alvarezii) biomass was investigated as a new biosorbent of methylene blue from aqueous solution. The effect of operational parameters such as equilibrium pH, agitation time, initial dye concentrations and biosorbent dosage on the biosorption capacity of Kappaphycus alvarezii was studied. The equilibrium solution pH was found to profoundly affected methylene blue sorption capacity of Kappaphycus alvarezii with pH 8 found to be optimum. Evidence from Fourier-transform infrared spectroscopy and scanning electron microscopy pictures confirmed the dye biosorption mechanism as electrostatic interaction between the negatively charged seaweed surface and positively charged methylene blue. Biosorption isotherms indicated that Kappaphycus alvarezii exhibited methylene blue uptake of 74.4 mg/g, according to the Langmuir model. The equilibrium isotherm data were evaluated using the Freundlich, Langmuir, Redlich-Peterson and Toth models. Kinetic studies revealed that methylene blue uptake was fast with 97% or more of the uptake occurred within 60 Downloaded by [University of Cincinnati Libraries] at 21:26 03 January 2015A c c e p t e d M a n u s c r i p t 2 min of contact time. The pseudo first and second order models were applied to describe kinetic data, of which the pseudo-first order described experimental data better with high correlation coefficient and low percentage of error values.
