“…The removal of heavy metal ions from wastewater typically involves traditional chemical precipitation, redox reaction, ion exchange, adsorption, evaporation, electrolysis, and membrane methods (Kang et al, 2004(Kang et al, , 2011Kagramanov et al, 2010;Li et al, 2011;Mamba et al, 2009;Navarro et al, 2005). The microbiological method has been extensively used because of its cost effectiveness, superior performance, and environmental friendliness.…”

“…A number of specialized processes have been developed for the removal of metals from waste discharges. These include chemical precipitation (Ku and Jung, 2001), coagulation/flocculation (Samrani et al, 2008), ion exchange (Kang et al, 2004), electrochemical operations (Wang et al, 2007), biological operations (Pavasant et al, 2006), adsorption (Fu and Wang, 2011), filtration, and membrane processes (Landaburu-Aguirre et al, 2009). The choice of method is based on the concentration of the metal ions in the solution and the cost of treatment (Richardson and Harker, 2002).…”

Solvent extraction is an energy-efficient technology which uses two immiscible phases. In this regard, solvents like hydrophobic 1-butyl-3-methylimidazolium hexafluorophosphate based ionic liquids have been used. The hydrophilicity of the metal ions is a challenge to use this method. Coordinating the metal ions by ligands, lowering the pH of the aqueous phase, modifying the ionic liquid itself in such a way that it can coordinate with the metal ions, employment of large ionic liquid to aqueous phase ratio (minimum of 1:1) were also the attempts made to improve the distribution coefficient of the ionic liquids. All these efforts are problematic in hindering the applications of ionic liquids in extraction. In this report, the extraction efficiencies of ionic liquids ]) from water samples containing Cd 2+ using very small ionic liquid to water ratio (1:6 and 1:12) from a solution of concentrations 0.005 mg/L with out using any coordinating agent as an extractant and the need of changing the pH are disclosed. While ionic liquids to aqueous phase ratio 1:12 demonstrated extraction efficiencies of 75%, 83.75%, 87.50% and 100%, respectively; the 1:6 ratio extracted 87.50%, 100%, 100% and 100%, respectively which shows suitability of the later ratio for better extraction. Moreover, the recyclabilities of [C 6 mim] [PF 6 ] and [C 8 mim] [PF 6 ] was investigated and the result showed that they can be used at least for five cycles. A Linear calibration curve with good coefficient of determination was obtained during the analysis for determination of the metal in the extracts.
