“…Phenol forms a binary azeotrope with water at 9.2 wt % of phenol, which is hard to separate by distillation. Moreover, the removal of phenol and phenolic compounds from wastewater has taken on great environmental interest over the last years [4], [5]. Therefore, recovery of phenolic compounds from aqueous solution using liquid-liquid extraction method is industrially and economically important [6].…”

Abstract-This study demonstrates experimental solubility and tie-line data for the (water + phenol + isobutyl acetate) system at T = 308.2 K and atmospheric pressure. This ternary system exhibits type-2 behavior of LLE. To evaluate the extracting capability of the solvent, distribution coefficients and separation factors were calculated. The consistency of the experimental data was determined through the Othmer-Tobias and Bachman equations. The experimental data were correlated using the NRTL and UNIQUAC models, and binary interaction parameters were obtained. The average root mean square deviation values between the experimental and calculated data show the capability of these models.

“…Its wastewater is primarily from the coke, petrochemical, resin t, insulating material, chemical and plastics plants, perfumery, etc [1,2,3]. It exists in the coal tar and various liquefied and gasified products, being one of the mainly used products in the coal processing.…”

“…However, the manner in which the phenolic substance is recovered shall be based on comprehensive consideration of various technological and economic factors. Researchers of both home and abroad have worked much on the phenolic wastewater treatment and the phenolic substance recovery for many years, having learned different methods such as chemical and biochemical phenol removals [5,8,9,10], but the purpose of a majority of these methods is to oxidize the phenol compound into an innoxious substance such as CO 2 and H 2 O, thereby making it impossible to recover a large amount of valuable phenol.…”

SynthesisLiquid membrane separation PhenolWastewater treatment a b s t r a c tThe environmental pollution of phenol is primarily taken as a result of wastewater discharged from some special chemical plants. It is the common pollutant to be controlled in industrial wastewater, and therefore, how to effectively minimize its environmental pollution by the phenolic pollutants treatment and recovery becomes an important subject. This paper aims to make a study on the support liquid membrane separation from phenolic wastewater in hydrated environment. The process of separation is conducted with hydrophobic ionic liquid 1-butyl-3-methylimidazole hexafluorophosphate [BMIM]PF 6 prepared by the microwave synthesis method based on fundamental solvent extraction research and applied to the inner coupling liquid membrane system. as the purpose is to migrate phenol in the simulated wastewater and survey the temperature, stirring speed, feed liquid phase acidity, initial concentration and NaOH concentration in the stripping phase influence on the phenol migration to obtain the preferred condition for migration.The said condition is as follows: The temperature of 300 K, the stirring speed ranging from 350 to 400 rpm, the feed liquid phase pH of 3.65, and NaOH concentration of 0.8 mol/L in the stripping phase. In the system, phenol is approximated to 100% in migration rate and the ionic liquid may be recycled for several times.

“…Liquid extraction is an efficient method to treat cresolcontaining wastewater [4], and liquid-liquid equilibria (LLE) data are essential for experiment or simulation study of extraction process [5]. Some authors have reported LLE data for aqueous solutions of cresol with various organic solvents.…”
