“…Similarly, some researchers have found that the Freundlich K F for As adsorption on soils correlates significantly with the amounts of CBD-extractable Fe (Zhang and Selim 2005), total Fe, and ammonium oxalate-extractable Fe (Osorio-López et al 2014). Although those studies suggested that As adsorption was closely correlated with Fe content of sediment samples, effects of variables such as , contact time=8 h, pH of 5, 7, or 9, at 25°C).…”

“…Sequential extraction technique has been widely used to assess the geochemical partitioning and chemical binding of As in solids (Han et al 2004;Devesa-Rey et al 2008;Doušová et al 2008;Qi and Donahoe 2008;Costagliola et al 2013;Kim et al 2014), and to evaluate adsorption fraction and desorption (Zhang and Selim 2005;Osorio-López et al 2014). This method offers a great promise to distinguish effects of interacting factors and to understand the roles of the interacting factors in chemical binding of adsorbed As.…”

Effects of pH, As species, and Fe/Mn minerals on the fractions of adsorbed As in aquifer sediments were evaluated. Kinetic data showed that As adsorption was controlled by diffusion through the external film. Isothermal data of both As(III) and As(V) fitted the Langmuir isotherm well, revealing a monolayer adsorption process. Sequential extraction demonstrated that water-soluble As and non-specifically sorbed As were the major fractions of adsorbed As. Assessing the relationship between the Freundlich K F and the increases in the amounts of As fractions showed that the pH played a key role in weakly adsorbed As, especially water-soluble As. Although inorganic As species converted each other during the adsorption processes, more non-specifically sorbed As was adsorbed in As(V)-treated sediment than in As(III)-treated sediment, showing that the electrostatic selectivity controlled the non-specific adsorption.Additionally, specifically sorbed As and As associated with the amorphous phases were predominated by Fe/ Mn minerals, especially Fe(III) (hydr)oxides. These results suggested that pH, As species, and Fe/Mn minerals would regulate the As fractions in aquifer sediments, and therefore control As cycling in aquifer systems.

“…tigated the effectiveness of mussel shell waste amendment to increase As retention on diverse solid materials (SecoReigosa et al, 2013a, b;Osorio-López et al, 2014), and this amendment could also be useful to increase As retention on granitic substrates (such as mine spoils or exposed C horizons), which has not been studied up to now.…”

Abstract. As(V) adsorption and desorption were studied on granitic material, coarse and fine mussel shell and granitic material amended with 12 and 24 t ha −1 fine shell, investigating the effect of different As(V) concentrations and different pH as well as the fractions where the adsorbed As(V) was retained. As(V) adsorption was higher on fine than on coarse shell. Mussel shell amendment increased As(V) adsorption on granitic material. Adsorption data corresponding to the unamended and shell-amended granitic material were satisfactory fitted to the Langmuir and Freundlich models. Desorption was always < 19 % when the highest As(V) concentration (100 mg L −1 ) was added. Regarding the effect of pH, the granitic material showed its highest adsorption (66 %) at pH < 6, and it was lower as pH increased. Fine shell presented notable adsorption in the whole pH range between 6 and 12, with a maximum of 83 %. The shellamended granitic material showed high As(V) adsorption, with a maximum (99 %) at pH near 8, but decreased as pH increased. Desorption varying pH was always < 26 %. In the granitic material, desorption increased progressively when pH increased from 4 to 6, contrary to what happened to mussel shell. Regarding the fractionation of the adsorbed As(V), most of it was in the soluble fraction (weakly bound). The granitic material did not show high As(V) retention capacity, which could facilitate As(V) transfer to water courses and to the food chain in case of As(V) compounds being applied on this material; however, the mussel shell amendment increased As(V) retention, making this practice recommendable.

In literature, easily obtainable, economical and biodegradable natural materials such as mussel shells have attracted great interest that can be used for different aims such as biodiesel production [2,3], nanoscience [4], dye [5][6][7] and metal removing [8][9][10][11][12] and synthesis studies [13][14][15][16].…”

In recent years, developing economical adsorbents to treat with different types of pollutants has attracted great interest. Waste mussel shells are common wastes produced by the seafood industry. They have some advantages over conventional process such as simplicity of design and low cost. In this study, the uncalcinated and calcinated mussel shells were characterisated for their surface characteristics. Mussel shells washed with tap water several times followed by distilled water and dried at 105°C for 12 hours in an oven. They were powdered to small particles and calcined at 900°C for 2 hours. The sample was finely ground into small particles of different sizes, washed with distilled water and dried overnight at 105°C. And then, the sample was calcined at a heating rate of 2°C/min to 400°C and maintaned at this temperature for 4 hours.The calcined and uncalcined mussel shell samples were characterised by Fourier transformed infrared spectroscopy, scanning electron microscopy equipped with an energy dispersive spectrometer, Brunauer-Emmett-Teller and Zeta potential mesaurements. The results indicated that calcination studies improved the surface charasteristics of the mussel shells and that the calcinated mussel shells can be used in adsorption studies as a novel low-cost, eco-friendly biosorbent efficiently.
