Effect of types of adjuvants on the partition efficiency of BSA. Neutral salts, such as NaCl and KCl, and ILs, such as [Bmim]BF₄, [Emim]BF₄, [Bmim]Br and [Emim]Br, were added at a fixed concentration of 1% (w/w) to the 35% (w/w) 1-propanol/22% (w/w) maltose ABS at pH 5.0 as adjuvants to evaluate the effect of types of adjuvant on the K and Y of BSA. The results are expressed as mean ± standard deviation of triplicate readings
