“…The functional groups of the S. platensis biomass were identified using infra-red analysis (FT-IR) (Prestige 21, the 210045, Japan) (Mona et al, 2011). The specific surface area, pore volume and average pore radius were determined by standard BET N 2 -adsorption methods (Quantachrome, Nova station A, USA) (Schimmel et al, 2010).…”

“…Many biosorbents have been used to remove dyes from aqueous solutions, such as, Chlorella vulgaris (Aksu and Tezer, 2005), Azolla rongpong (Padmesh et al, 2006), Aspergillus foetidus (Patel and Suresh, 2008), Aspergillus parasiticus (Akar et al, 2009), Ulothrix sp. (Dogar et al, 2010) and Nostoc linckia (Mona et al, 2011), but studies about the use of S. platensis are very limited. S. platensis, a member of blue-green algae, contains a variety of functional groups such as carboxyl, hydroxyl, sulfate, amine, phosphate and other charged groups on the surface, which can sequester pollutants (Seker et al, 2008).…”

-The equilibrium and thermodynamics of azo dye (tartrazine and allura red) biosorption onto Spirulina platensis biomass were investigated. The equilibrium curves were obtained at 298, 308, 318 and 328 K, and four isotherm models were fitted the experimental data. Biosorption thermodynamic parameters (ΔG, ΔH and ΔS) were estimated. The results showed that the biosorption was favored by a temperature decrease. For both dyes, the Sips model was the best to represent the equilibrium experimental data (R 2 >0.99 and ARE<5.0%) and the maximum biosorption capacities were 363.2 and 468.7 mg g -1 for tartrazine and allura red, respectively, obtained at 298 K. The negative values of ΔG and ΔH showed that the biosorption of both dyes was spontaneous, favorable and exothermic. The positive values of ΔS suggested that the system disorder increases during the biosorption process.

“…In the manner, reactive dyes are mainly employed in dying paper and textile industries that release large flows from colored wastewater [8]. Many triers to remove the wastewater in different physical, chemical and biological methods were done such as photocatalytic decolorization [8] [9] [10], adsorption [11] [12] [13], bio-removal [14] [15], photo fenton and fenton-like [16] [17] extraction [18], Coagulation [19] [20] and using dielectric barrier discharge [21].…”

Zinc sulfide photocatalysts doped with chromium (1:1)% were synthesized via precipitation technique. Their characteristics were studied by X-ray diffraction (XRD), AFM and Florescence spectrometer. The photocatalytic reaction was applied under light intensity equal to 1.45 × 10 −7 Einstein mol-1 to investigate the kinetics and thermodynamic parameters for photo-decolorization of reactive black 5 dye in collide solution of bare and Cr-doped ZnS. The mean crystal size and particle size for bare ZnS are more than those values for prepared Cr loaded ZnS.

“…Recently, inexpensive, ecofriendly and not pathogenic organisms have been used for the dye removal [18]. In this respect, the biosorption process has attracted a great interest in this context, and seems a good alternative for the removal of dyes and other pollutants from wastewaters [19,20], as a replacement for costly commercially biosorbents [21]. It can be defined as sequestering of organic or inorganic compounds by alive or dead biomasses or their derivatives; the biomass can consist of bacteria [22], fungal [19], yeasts [22], algae [23], seaweeds and even industrial or agricultural wastes [24,25].…”

In the present study, biomass fiber (Luffa cylindrica) has been successfully used as biosorbent for the removal of a cationic dye namely, methylene blue, from aqueous solution using a batch process. The characterization of the biosorbent was carried out by the infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The chemical composition has been established by the energy dispersive X-Ray spectroscopy (EDS). The effects of various parameters such as the contact time (0-160 min), solution pH (2-10), biosorbent dose (0.5-8 g L -1 ), particle size, initial MB concentration (20-300 mg L -1 ) and temperature (20-60°C) were optimized. The biosorption isotherms were investigated by the Langmuir, Freundlich, Dubinin-Radushkevich and Tempkin models. The data were well fitted with the Langmuir model, with a maximum biosorption capacity of 49.46 mg g -1 at 20°C. The kinetics data were analyzed by the pseudo-first-order and pseudo-second-order models. The mass transfer model in terms of interlayer diffusion was applied to examine the mechanisms of the rate-controlling step (R 2 = 0.9992-0.9999). The thermodynamic parameters: free energy (DG°= -5.428 to -3.364 kJ mol -1 ), enthalpy (DH°= -20.547 kJ mol -1 ) and entropy (DS°= -0.052 kJ mol -1 K -1 ) were determined over the temperatures range (20-60°C). The results indicate that Luffa cylindrica could be an interesting biomass of alternative material with respect to more costly adsorbents used nowadays for dye removal.
