    Abstract: A solid/liquid phase process for the separation and recovery of an anionic dye from an aqueous solution is disclosed. The solid phase comprises separation particles having surface-bonded poly(ethylene glycol) groups, whereas the aqueous solution from which the anionic dye molecules are separated contains a poly(ethylene glycol) liquid/liquid biphase-forming amount of a dissolved lyotropic salt. After contact between the aqueous solution and separation particles, the anionic dye is bound to the particles. The bound anionic dye molecules are freed from the separation particles by contacting the anionic dye-bound particles with an aqueous solution that does not contain a poly(ethylene glycol) liquid/liquid biphase-forming amount of a dissolved lyotropic salt to form an aqueous anionic dye solution whose anionic dye concentration is preferably higher than that of the initial dye-containing solution.

    Abstract translation: 公开了一种用于从水溶液中分离和回收阴离子染料的固相/液相方法。 固相包括具有表面键合的聚（乙二醇）基团的分离颗粒，而分离阴离子染料分子的水溶液含有聚（乙二醇）液/液双相形成量的溶解的致盐盐。 在水溶液和分离颗粒接触之后，阴离子染料与颗粒结合。 通过使阴离子染料结合的颗粒与不含聚（乙二醇）液体/液体双相形成量的溶解的致盐盐的水溶液接触来形成阴离子型阴离子染料分子， 其阴离子染料浓度优选高于初始含染料溶液的染料溶液。
