摘要： A process for the removal of difficult-to-remove acidic organic compounds from aqueous solutions using novel phosphine oxide mixtures in which mixtures 1) at least two phosphine oxides are present, the total number of carbon atoms in a first oxide being at least 15 and the difference in the total number of carbon atoms in the first and second oxides being present in an amount of at least 5% by weight and not more than 60% by weight or 2) at least four phosphine oxides are present, the total number of carbon atoms in an oxide having the lowest no. of C atoms being at least 15, said phosphine oxides being present in an amount of at least 1% by weight and not more than 60% by weight. Unexpectedly high extractability is achieved using the mixtures.
