“…To increase the phenol sorption, the amount of capsules in different sorption experiments was increased from 0.1 to 2 g (Figure 4). As expected, an increase in the Ph sorption is observed due to an increase of available sites for the extraction process [36]. Therefore, further experiments were performed with 2 g of capsules.…”

Microcapsules of cellulose acetate with Cyanex 923 were prepared and used in this study for phenol removal from water and synthetic textile wastewater. The influence of several factors on the microcapsules extraction efficiency was studied, as well as characterization and phenol adsorption isotherm. Microcapsules characterization demonstrated the extractant reagent encapsulation, while in a batch mode procedure, good adsorption of phenol (ca. 5.5 × 10−3 mol Kg−1) has been reached. A slight decrease in phenol extraction percentage was obtained when synthetic textile wastewater was used (ca. 4.955 × 10−3 mol Kg−1), although a decrease in color was observed due to dye microcapsule extraction. Results indicate that this method is a promising alternative to conventional phenol removal technologies for aqueous samples of low phenol concentrations or in textile effluents.

“…This is due to the change of clay surface properties and the metal species with pH change. Figure 3 illustrates that the maximum sorption for strong electric field and electrostatic effects may become the dominant factor such that small ions, which have a higher charge density, are bound more strongly [24]. The sorption% of metal ions increases as the pH increases and reaches the maximum at pH 5.5 and 4.5 for Cr(III) and Cu(II) ions, respectively, then decreases as the pH continues to increase.…”

The adsorption of Cu(II) and Cr(III) ions by pure clay mineral, vermiculite, was examined in aqueous solution with respect to the adsorbent dose, initial metal ion concentration, pH, and contact time. The studies showed that vermiculite can be used as an adsorbent material for the moderate removal of Cr(III) and Cu(II) from aqueous solutions. Lagergren first-order, pseudo-second-order, and intraparticle diffusion models were used to describe the kinetic data. The kinetics of adsorption indicates that the process fitted well the intraparticle diffusion model.

“…Adsorption is a highly recommended technique for properly treating wastewater, when there are ions in solution. Traditionally used materials such as chitosan (Bratskaya et al, 2009;Shen et al, 2013), activated carbon Naushad, 2012;Galiatsatou;Metaxas;KasselouriRigopoulou, 2002), inorganic ion exchange resins (Gupta;Singh;Rahman, 2004;Jha et al, 2009), zeolites Karapinar;Donat, 2004;Peng, 2010), or some combination of these (Wan Ngah et al, 2012;Yuan;Liu, 2013), can be used to remove metal ions, such as Ag, Cd, Co, Cr, Cu, Hg, Mn, Ni, Pb and Zn from an aqueous medium.…”

The wastewater produced by the galvanoplasty industryis a serious environmental problem due to the high concentrations of heavy metals. In this study polymers were used in ionic flocculation to treat synthetic wastewater containing metals, applying four types of polyacrylamides with different ionic loads as agents to remove copper and zinc. Metal removal efficiency was assessed considering the influence of polymer concentration, ionic load and pH. Selectivity (Cu 2+ /Zn 2+ ) at different polymer concentrations was also evaluated. The results confirm that polyacrylamide is efficient in treating wastewater containing heavy metals. These experiments exhibited removal efficiency of around 40% and pH= 4,5; however, efficiency was more than 80% with pH= 7.0 under the same conditions, when polyacrylamides with average ionicity were used.
