“…Apart from proteins like bovine serum albumin, lysozyme, trypsin, myoglobin (Pei et al, 2009, Du et al, 2007Dreyer & Kragl, 2008;Dreyer and Kragl, 2009) ATPS have been used for the recovery of small organic and inorganic molecules such as metal ions, radiochemicals, dyes, drug molecules (Huddleston et al, 1999;Willauer et al, 2002;Zhu et al, 2001;Bridges & Rogers, 2008). Short chain alcohols (Gutowski et al, 2003), phenol (Chen et al, 2009), testosterone and epitestosterone (He et al, 2005), penicillin G , opium alkaloids (Li et al, 2005a), L-tryptophan Ventura et al, 2009;Louros et al, 2010), antibiotics (Dominguez-Perez et al, 2010), caffeine and nicotine have been analysed as partitioning solutes so far. Biphasic liquid systems could find special applications in countercurrent chromatography (CCC) where both the mobile and stationary phase are immiscible liquids.…”
