“…[1][2][3][4][5][6] Such adsorbents may be derived from various sources like minerals and lignocellulosic material, even though the AC production from minerals presents some important disadvantages like high cost, low yields in carbonization and high ash content. [7][8][9][10] Alternatively, lignocellulosic materials from agro--industrial and agricultural wastes such as peels, seeds or bagasse offer great potential to be used as raw carbon precursors due to their high carbon content and already proven high adsorption capacity.…”

carbons (ACs) with well-developed microstructure and high microporosity were obtained from biomass by potassium hydroxide activation. The preparation process consisted in producing carbon materials in the ratios of activating agent to raw material 70:30, 50:50, 30:70 and 25:75 (w/w) characterized by thermal analysis coupled to spectroscopy (TG-DTA / FT-IR), scanning electron microscopy (SEM), N 2 adsorption isotherms at -196 °C and activation isotherm at 500 and 600 °C for 3.0 h. Specific surface areas (SBET) within 728 and 1712 m 2 g -1 and (S mic ) within 1054 and 1923 m 2 g -1 were obtained, while the micropores surface area was calculated using the Dubinin-Astakhov (DA) equation and the pore size distribution calculated from density functional theory (DFT) was found to be in the range 1.09 -1.77 nm. Adsorption isotherms were fitted using Langmuir and Freundlich non-linear models and the adsorption capacity determined for methylene blue dye was between 27.13 and 459.20 mg g -1 .

“…The results showed that the amount of adsorption of dyes was found to be strongly related to solution pH and initial dye solution. The highest amounts of dye adsorption at pH 9 on coal bottom ash was attributed to an increasing basicity on both silica and alumina that led to a change from positive to negative and therefore enhances the sorption of the positive dye molecule [6]. The lowest dye uptake at acidic condition on coal bottom ash was probably due to presence of excess of H + ions competing with the dye cations for the adsorption sites.…”

“…The use of activated carbon in water treatment has been employed due to its broad spectrum of adsorption capacity however activated carbon is an expensive material. Several studies have been conducted to evaluate the feasibilitymany types of inexpensive adsorbents including Chitin/chitosan [4], fly ash,bottom ash [5,6,7], coal fly ash (CF), which is produced from the burning of coal in fired power plants and contains mainly of (SiO 2 ), alumina (Al 2 O 3 ), lime (CaO), and iron oxide (Fe 2 O 3 ), with a trace amount of unburned carbon [7].…”

Abstract. Removal of vertigo blue dye from batik textile wastewater was studied by adsorptionprocess onto activated carbon (AC) and coal bottom ash (CBA).The influence of experimental conditions (pH solution, dye concentration, and contact time) were studied on the both adsorbents. At equilibrium conditions, the data were fitted to Langmuir and Freundlich adsorption models. The maximum adsorption capacity calculated from the Langmuir model for carbon active was 6.29mg/g at pH that found to be considerably higher than that obtained for coal bottom ash 3.72mg/g pH 9. From Freundlich model, the maximum adsorption capacity is less for coal bottom ash (pH 9) than that for carbon active (pH4).

“…This rapid process of mass transfer may have occurred because the number of available active sites on the surface of the adsorbent material is more important at the start of the adsorption process than the active sites remaining after one-tenth of the time has passed (Yaneva and Koumanova 2006;Dincer et al 2007;Berez et al 2014;Sadegh et al 2015;Zare et al 2015).…”

This work reports new findings on the physisorption of Foron Blue 291 on natural bentonite under both static and dynamic flow conditions of the aqueous solution that may prove important when using the adsorption technique for wastewater treatment. The quantity of dye retained by the solid matrix under both ideal exchange conditions between dyes and adsorbents given in a batch reactor and a pulse injection of dissolved azo dye in a soil column composed of a mixture of mean grain-sized sand and bentonite at different flow rates and at various mass fractions of bentonite was studied. Column experiments involving the use of a non-reactive tracer (Fluorescein) were performed to examine hydrodynamic behaviours of the clay/sand mixture studied. It is shown that advective-dispersive transport across a clay/sand mixture may be characterized by a double porosity medium. The results obtained on the reactive transport of Foron Blue 291 underscore that Foron Blue 291 adsorption depends heavily on the mass fraction of clay in a clay/sand mixture. With a clay mass fraction of 30 %, 77 % of the dissolved Foron Blue 291 mass was irreversibly removed by the adsorbent. At low flow rates, removal ratios obtained from the dynamic reactive system were similar to those obtained through previous static reactor experiments.
