1. is separated from solution or mixture with foam, concentrates and/or the method for purified composition, it comprises the following steps:

  • By optionally affinity-foaming agent being bonded to described composition, modify composition that is to be separated, concentrated and/or purifying, to strengthen the affinity of described composition to foam;

    Wherein said affinity-foaming agent combines with target compound, and increases this target compound and be separated to tendency on foam surface;

    Wherein said affinity-foaming agent is selected from sophoroside, rhamnolipid, PMMA-co-PMAA-cellobiose, or its any combination;

    Bubble is introduced the solution containing the composition strengthened, thus is formed by the composition of described enhancing foam stable at least in part;

    WithFrom the composition strengthened described in described foam fraction factor, concentrated and/or purifying.
