“…The authors found the adsorption capacities of cotton for acid blue 25, acid yellow 99 and reactive yellow 23 to be 589, 448 and 302 mg g À1 , respectively. Adsorption behaviour of direct dye on cotton in Aerosol-OT (AOT) reverse micellar system was studied by Sawada and Ueda (2003), exhaustion of dye was suggested to be perfect and superior to that in aqueous system. In a study to evaluate the performance of cotton waste for dye removal, McKay et al (1999) found that the cotton waste had the potential to adsorb 875 and 277 mg g À1 of basic red 2 and basic blue 9, respectively.…”

“…Among these techniques, adsorption is generally preferred due to easy handling, high efficiency, low energy input, and availability of different adsorbents [6,7]. Wastewater treatment has been studied using clay/basic [8], chitosan [9], cotton [10], montmorillonite [11], sepiolite/methyl green, and natural zeolite/basic [12]. However, the application of these materials is practically limited because the adsorbent is not available in sufficient amounts.…”

We report herein on the fabrication of carbonaceous material produced from cotton treated with Tricresyl phosphate (TCP) for fireproofing and its evaluation for adsorbing Methylene blue (MB). We prepared two carbonaceous materials: cotton calcined at 900• C (CT900) and cotton calcined at 900• C with TCP (F-CT900). These materials were evaluated in terms of their scanning electron microscope images, specific surface area, pore volume, mean pore diameter, and solution pH. We found that the specific surface area of F-CT900 (1492 m 2 /g) is greater than that of CT900 (910 m 2 /g), and that the mean pore diameter of F-CT900 (2.41Å) is smaller than that of CT900 (9.09Å). The adsorption of MB onto CT900 and F-CT900 reached equilibrium within 5 h. We fitted the experimental data with the pseudo-second-order model and obtained correlation coefficients between 0.993 and 0.999. We found that more MB adsorbed onto F-CT900 (about 650 mg/g) than onto CT900 (about 350 mg/g). We also fitted these experimental data with both the Freundlich and Langmuir equations. Thus, carbonaceous material for MB removal could be produced from fireproofed cotton, and it is useful for the purification of dye solution systems.

“…Both granular or powdered activated carbon (AC) [9][10][11][12][13] and different low cost adsorbents (LCA) like coir pith [14], clay [15], bagasse, fly ash [16], mesoporous minerals [17], sawdust [18], alunite [19], banana peel [20], biomass [21,22] and others adsorbent like polymer [23], cotton [24] etc are used for removal of toxic dyes from effluent. Adsorption capacities of commercial AC for reactive dyes generally vary from 7.69 to 1179 mg/g [25].…”
