“…Its disposal has always been a matter of concern to the station authorities, as the dumped ash is considered highly unsuitable for the agricultural utilization (Gupta et al 2004). Already it is proved that bottom ash is very efficient adsorbent for removing malachite green (Gupta et al 2004), 2-Aminophenol (Gupta et al 2006), Basic fuchsin (Gupta et al 2008), Chrysoidine Y (Mittal et al 2010 and Crystal Violet (Nidheesh et al 2011). The paper presents adsorption kinetics and equilibrium uptake of fluoride over bottom ash.…”

“…2009). Even though activated carbon, a common adsorbent used in water and wastewater treatment, showed advantages, the main drawback of the activated carbon is the cost and difficulty in regeneration (Liu et al 2007). Therefore, in recent years, this has prompted a growing research interest in the production of activated carbons from renewable and cheaper precursors which are mainly industrial and agricultural by-products (Tan et al 2008).…”

Millions of people rely on drinking water that contains excess fluoride. In fluoride endemic areas, especially small communities with staggered habitat, defluoridation of potable water supply is still a problem. In this study, adsorption potential of bottom ash was investigated for defluoridation of drinking water using batch and continuous fixed bed column studies. Batch sorptive defluoridation conducted under experimental conditions such as pH, temperature, particle size, agitation time and dosage. Adsorption isotherms have been modeled by Langmuir and Freundlich isotherms. The fluoride sorption capacity at a breakthrough point for bottom ash was greatly influenced by bed depth. The results were then analyzed using the Bed Depth Service Time (BDST) Model, and various performance parameters like Adsorption Capacity, Critical Bed Depth, and Adsorption Rate Constant were evaluated. With the observed data the Thomas model and the Yoon Nelson model fitted well and the constants were found.

The sorption of from aqueous solution on AFN membrane has been studied and the equilibrium isotherms determined. The experimental data have been analyzed using the Langmuir, Freundlich, Temkin and Dubinin-Radushkevich isotherm models at different temperatures varying from 283 to 313 K. The results were analyzed using three kinetic models, Lagergen first order, second order and the Elovich model. The obtained results show that the best-fit correlation of the experimental data was obtained using the second order model. Thermodynamic parameters for the adsorption system were determined at 283, 298 and 313 K.

The aim of this work is to study the thermodynamic and kinetic studies with regard to the adsorption of Acid Green 9 (AG9) on the most efficient resin, namely, acrylic weak base anion exchange resin with ethylenediamine-functional groups (A1) selected from several anion exchange resins. The influence of the various experimental parameters such as, pH, initial dye concentration, contact time, temperature, and adsorbent dose was investigated by batch experiments. The extent of the dye adsorption increased with the decrease of the initial dye concentration and the increase of the contact time, temperature, and amount of the adsorbent. Adsorption process was quantitative and very fast at low concentrations of the dye. To investigate the mechanism of the adsorption and potential rate-controlling steps, pseudo first-and secondorder, as well as intraparticle diffusion kinetic equations have been used. The adsorption kinetic of AG9 dye from aqueous solution onto A1 could be described by the pseudo second-order reaction model. The obtained results are in agreement with the Langmuir and Freundlich models. In the optimum conditions established, an adsorption capacity of 500 mg textile dye (72% purity) g À1 adsorbent (at 293 K) was reached. Desorption experiments by batch and dynamic methods were performed using a solution of 0.05 mol L À1 NaOH. A series of 13 adsorption-desorption cycles were carried out by the dynamic method with a quantitative adsorption and the desorption efficiency higher than 95%.
