“…This phenomenon is similar with the adsorption performance of other pollutants (i.e. phosphate or dyes) onto Fe-based sludge [6,31]. Moreover, the R 2 results implied the adsorption kinetics of As(III) on FBBS can be satisfactorily described by either the Elovich model or the Power model.…”

“…However, many of them are restricted for engineering application due to their high prices. Researchers have made efforts on the use of waste materials as low-cost adsorbents for the removal of pollutants from wastewater [4][5][6]. It has been widely recognized that the reuse of a waste material as low-cost adsorbent to remove As from wastewater could not only decrease the cost of wastewater treatment, but also reduce the amounts of these solid wastes.…”

“…Industrial sludge could be used for deriving adsorbents, which can be used for treatment of wastewater. Tannery sludge (Reddy et al, 2008;Geethakarthi and Phanikumar, 2011), paper mill sludge (Khalili et al, 2000;Khalili et al, 2002), poultry litter (Guo et al, 2010), agriculture byproduct (Ng et al, 2010), sewage sludge ash (Ferreras et al, 2010;Pan et al, 2003;Liu et al, 2010;Yu et al, 2006) and water treatment plant sludge (Kayranli, 2011;Zhou et al, 2010) derived adsorbent can be used for treatment of industrial wastewater as well as domestic sewage. Textile mill sludge also has potential to be used as adsorbent for removal of dyes from dye wastewater.…”

Textile industry is one of the largest and oldest industries in India. Textile mill uses large quantities of water for its variety of wet processes, which in turn generates a large amount of waste water. Effluent treatment plants treat textile mill waste water using a variety of chemical coagulants thus producing greater amount sludge. Disposal of sludge is a challenging problem. In this study Textile mill sludge was incinerated at 800 o C and used as an adsorbent without any activation. SEM images confirmed that, sludge ash was porous in nature and could be used as an adsorbent. For the entire study, Remazol blue dye was used. Experimental studies were carried out in an acidic pH range, showed good dye removal by using incinerated textile mill sludge ash. Experimental results obtained fitted well in Langmuir and Freundlich isotherms.

“…The positive value of ∆H o indicates that the process was endothermic in nature 34 . The positive value of ∆S o shows that the increased randomness at the solid/solution interface 35 with some structural changes in the adsorbate and adsorbent and an affi nity of the adsorbent toward AB dye on Zizyphus oenoplia seed.…”

This article presents the feasibility for the removal of Aniline Blue dye (AB dye) from aqueous solution using a low cost biosorbent material Zizyphus oenoplia seeds. In this study, a batch mode experiments of the adsorption process were carried out as a function of pH, contact time, concentration of dye, adsorbent dosage and temperature. The experimental data were fi tted with Freundlich and Langmuir isotherm equations. The feasibility of the isotherm was evaluated with dimensionless separation factor (R L ). The kinetic data of sorption process are evaluated by using pseudo-fi rst order and pseudo-second order equations. The mode of diffusion process was evaluated with intra-particle diffusion model. The thermodynamic parameters like change in enthalpy (∆H o ); change in entropy (∆S o ) and Gibbs free energy change (∆G o ) were calculated using Van't Hoff plot. The biosorbent material was characterized with Fourier Transform Infrared (FTIR) spectroscopy and the morphology was identifi ed with Scanning Electron Microscope (SEM) in before and after adsorption of AB dye.
