Local clay from Al-Madinah Al-Munawwarah was modified by a solution of cetyltrimethylammonium bromide (C16TMABr) at different initial concentrations. The organoclays were characterized by PXRD, TGA, FTIR and N 2 adsorption isotherms. The ability of these samples to remove the dye eosin is evaluated. The removal properties of organoclays were dependent on the content of C16TMA cations, the initial concentrations of eosin, temperature of the removal process, the mass of the used organoclays. These organoclays exhibited removal percentages in the range of 80 ~100% and removed amounts of 50 ~ 68 mg of eosin/ g. The isotherms were fitted well in Langmuir model.

“…Mostly, biosorbents have revealed valuable because of their good binding capability toward various dye groups (Crini 2006;Ju et al 2008;Vijayaraghavan et al 2008). Sorption mechanisms involve adsorption, chelation, ion-exchange, complexation and binding behavior depends upon pollutant's chemical nature, biosorbent's type and conditions such as ionic strength, temperature and pH.…”

“…On the basis of dyeing process, textile dyes are classified as basic dyes, acid dyes, reactive dyes, disperse dyes, direct dyes and vat dyes (Murugesan et al 2006). Usage of reactive dyes is predominant due to their binding capacity through covalent bond with textile fibers and their affirmative individuality such as water-fasting, color brightness and simple appliance techniques (Fernandez et al 2008;Ju et al 2008;Deniz and Karaman 2011). Azo-based chromophores of reactive dyes show compatibility with a verity of reactive groups such as difluorochloropyrimidine vinyl sulfone, trichloropyrimidine and chlorotriazine (Vijayaraghavan and Yun 2007;Junxiong et al 2009;Sadettin and Donmez 2006;Handan 2011).…”

Removal of color water pollution due to Reactive Orange 122 dye was investigated using an inexpensive, locally available Trapa bispinosa. Fruit and peels of T. bispinosa biomass was used for this context in free, polyvinyl alcohol immobilized and chemically (H 2 O 2 ) treated form. The aftermath of operational parameters such as pH (1.0-6.0), dye initial concentration (10-350 mg L -1 ) and contact time (0-1,440 min) was investigated for maximum removal of dye from aqueous solution. Analysis was performed on UV-Vis spectrophotometer before and after sorption phenomenon. Maximum uptake was observed at pH 1.0. Highest q (mg g -1 ) was shown by H 2 O 2 -treated T. bispinosa fruit (46.36) and H 2 O 2 -treated T. bispinosa fruit beads (43.00). The sorption rate was rapid in first 30 min, and equilibrium was established in 120 min. It was observed that best model was pseudosecond order, with correlation coefficient in the range of 0.987-1.00. Langmuir model effectively described the sorption data with X m and R 2 that were in good agreement with experimental q (mg g -1 ). Regeneration of the sorbent was done by performing desorption cycles, which made the method environment-friendly and more economical. Surface morphology and elemental analysis of a sample were carried out.

“…Dye effluents are toxic, not only to the aquatic biota, but also to mankind. Aquatic biota is affected when dyes are present on the surface of water as the extent of photosynthesis of aquatic plants is reduced (Safa and Bhatti 2011;Ju et al 2008), while humans are affected as synthetic dyes would cause many health effects (Safa and Bhatti 2011;Rahchamani et al 2011).…”

Biosorption of cationic dyes on breadfruit (Artocarpus altilis) peel and core

The purpose of this research is to investigate biosorption characteristics of two cationic dyes, methylene blue (MB) and methyl violet 2B (MV), on breadfruit (Artocarpus altilis) peel and core. Characterization of breadfruit waste was conducted using surface titrations, thermogravimetry, and Fourier transform infrared spectroscopy. The extent of interaction between dyes and each biosorbent was monitored by absorbance measurements, which was then used in isotherm, thermodynamics, and kinetics analysis. Biosorption of MB and MV on breadfruit peel and core reaches equilibrium in 150-180 min. All four systems under investigation (MB-breadfruit peel, MB-breadfruit core, MV-breadfruit peel, and MV-breadfruit core) show similar extent of dye removal of about 80% under the conditions employed. Biosorption of both dyes on both biosorbents follow the Langmuir adsorption isotherm model at the ambient pH, at which the breadfruit surface bears a negative charge. Kinetics of biosorption of MB on breadfruit waste is so fast that it is not possible to determine the order of adsorption kinetics at the concentration level employed. The rate of biosorption of MV on breadfruit waste is smaller and follows pseudo second order kinetics with rate constants of 153.5 and 31.7 g mmol −1 min −1 for peel and core, respectively. Thermodynamics studies conducted for each biosorption system provide negative ΔG Θ , ΔH Θ and ΔS Θ values with the maximum biosorption for MB at the ambient temperature of 24 °C, while that for MV is obtained between 40 and 50 °C. All four biosorption systems show spontaneity and exothermic behaviour to varying degrees.
