Back Extraction Sample Clauses

Back Extraction. Organic acids, nitrogen-containing compounds, phenolic compounds, and amino acids were removed from ILs by back extraction with aqueous solutions, making the necessary pH adjustments and the ILs were then quantitatively recovered after neutralization and evaporation of the solvent. For example, neutral nitrogen-containing compounds were recovered from [Bmim][Cl] by back extraction using water or methanol (Xie et al, 2008) and a 94-98% recovery of ferulic acid from [Bmim][PF6] was achieved with a 0.02 M NaOH aqueous solution (Xx et al., 2007). In another case, 99% of phenols present were removed from [Bmim][PF6] after back extraction with 0.1 mol L-1 NaOH aqueous solution (Fan et al., 2008) and amino acids were recovered from AAILs by adjusting the pH of the solution to 7.0 with HCl, thus neutralizing the amino group (Xxxx et al., 2010).
