“…In the last decade, increasing interest on the use of aqueous micellar solution has been found in the field of separation science (Liang, Wang, Xu, Li, & Qi, 2009;Purkait, Banerjee, Mewara, DasGupta, & De, 2005). Cloud point extraction (CPE) is an alternative suitable separation technique, which is based on the phase behaviour of non-ionic and zwitter ionic surfactants in aqueous solutions, which exhibit phase separation after an increase in temperature or the addition of a salting-out agent.…”

“…In recent time, the use of CPE for treating environmental wastewater has rapidly progressed. Some examples of dyes that have been separated through this method are toxic Congo red, eosin (Purkait et al 2005), nitrobenzene (Goswami et al 2011), rhodamine B (Pourreza et al 2008) and chrysoidine (Purkait et al 2006).…”

“…Recently, application of inorganic salts in enhancement of the CPE efficiency of nonionic surfactants has been reported in number of studies (Purkait et al 2005(Purkait et al , 2006Goswami et al 2011). However, the literature review revealed that very few reports are available for the use of ILs as an additive with nonionic surfactants in CPE for metal separation (Gao et al 2013;Bozkurt et al 2012), but no report is available for dye removal.…”

In the last decade, increasing interest on the use of aqueous micellar solution has been found in the field of separation science. The unique physical and chemical properties of ionic liquids make them most suitable candidates as an additive with nonionic surfactants in cloud point extraction. A surfactant-mediated cloud point extraction process has been adopted for the removal of Coralene red dye using tetraethyl ammonium tetrafluoroborate ionic liquid as an additive with nonionic surfactant Triton X-100. The detailed study on effect of various operating parameters such as temperature, time, concentration of surfactant, dye and IL on extraction of dye has been carried out to find out optimum conditions. The extraction of dye was found to be increased with temperature, time, surfactant concentration and IL concentration. A developed Langmuir isotherm was used to compute the feed surfactant concentration required for the removal of Coralene red dye up to an extraction efficiency of 90 %. The effect of temperature and concentration of surfactant and dye on various thermodynamic parameters was examined, and it was found that the values of DG Graphical AbstractKeywords Langmuir isotherm Á Nonionic surfactant Á Thermodynamic parameter

“…CPE method has been successfully employed for the preconcentration of metal ions [9][10][11][12] and organic compounds such as polycyclic aromatic hydrocarbons [13][14][15] , polychlorinated compounds 16 , vitamins [17][18][19] , dyes [20][21][22] and biomaterials 23 . CPE method can be easily combined with several analytical methods such as spectral [24][25][26] , inductively coupled plasma (ICP) 27 , atomic absorption 28,29 , chromatographic 30,31 , flow injection 32 .…”

Cloud point extraction (CPE) was carried out to extract Eosin B dye from aqueous solution using non-ionic surfactant Triton x-114. The enrichment of dye was determined by a spectrophotometric study. The effects of different operating parameters, e.g., concentrations of surfactant, salt, temperature, pH, the heating time, equilibration temperature and time of centrifuge have been studied. The extracted surfactant-rich phase was diluted with ethanol and its absorbance was measured at 533 nm. The calibration curve was linear in the range of 0.0067-0.7300 mgL -1 with r 2 =0.995. The detection limit, preconcentration and enrichment factor were obtained 1.08 ng mL -1 , 15.00 and 11.20, respectively. The effect of some foreign species including cations, anions and similar dye, fluorescein was also investigated. This method was applied successfully for determination of the amount of Eosin B in water samples.
