Synergic adsorption in the simultaneous removal of acid blue 25 and heavy metals from water using a Ca(PO3)2-modified carbon

Activated carbons for the removal of heavy metal ions: A systematic review of recent literature focused on lead and arsenic ions

“…Specifically, heavy metals are discharged by industries such as agrochemical, petrochemical and fertilizers, whereas dyes are found principally in effluents of dye manufacturing industries, electroplating factories, distilleries and food companies [30,65]. It was further reported that an anionic dye favored the electrostatic interactions with heavy metals or might create new specific sites for the adsorption process [64].…”

Application of anaerobic granular sludge for competitive biosorption of methylene blue and Pb(II): Fluorescence and response surface methodology

“…Nevertheless, the treatment of these multi-component practical wastewater scenarios (i.e. heavy metals-dyes) is complex and requires effective purification processes (Tovar-Gomez et al, 2012). In particular, of all these above mentioned methods, biosorption is recognized as one of simplest and most cost-effective techniques for treating a variety of pollutants.…”

Analysis of synergistic and antagonistic adsorption of heavy metals and acid blue 25 on activated carbon from ternary systems

“…The surface chemistry of this adsorbent was chemically modified for enhancing its adsorption properties using wastes of egg shell (Guijarro-Aldaco et al, 2011;Tovar-Gómez et al, 2012). Fig.…”

“…For example, the wastewaters of textile industries contain a variety of inorganic and organic pollutants including heavy metals and acid dyes, which are generated from different textile process operations, e.g., scouring, bleaching and dyeing (Ozturk et al, 2009). Despite this fact, studies on the simultaneous adsorption of dyes and heavy metals have been mainly focused on binary dye-metal mixtures (Wang and Ariyanto, 2007;Visa et al, 2010;Tovar-Gómez et al, 2012). Furthermore, results reported in other studies indicate that this type of multicomponent systems (i.e., dye + heavy metals) may show both competitive and synergistic adsorption depending mainly on the dye chemical nature.…”

“…In this article, we have studied the multicomponent adsorption of AB25 dye and heavy metal ions Ni 2+ , Cd 2+ , Zn 2+ in ternary systems using an activated carbon that has been chemically modified with the wastes of egg shell (GuijarroAldaco et al, 2011;Tovar-Gómez et al, 2012). The performance of this adsorbent for removing multiple adsorbates has been studied using the ternary mixtures: AB25-Zn 2+ -Ni 2+ , AB25 -Zn 2+ -Cd 2+ and AB25-Ni 2+ -Cd 2+ .…”
