| description | The invention discloses a preparation method of resin for high-selectivity adsorption of gardenia yellow. The preparation method comprises the following steps: (1) adding a skeleton raw material, a cross-linking agent and an additive to de-ionized water for conducting a polymerization reaction namely, warming up mixed liquor to 60-80 DEG C within 35-55min and preserving heat for 0.5-2.5h; then warming up the mixed liquor to 60-80 DEG C within 15-20min and preserving heat for 3-5h; and then warming up the mixed liquor to 70-90 DEG C within 20-25min and preserving heat for 3-5h; finally, warming up the mixed liquor to 90-95 DEG C within 20-25min and preserving heat for 3-5h, and conducting solid-liquid separation; (2) cleaning solid phase with water for 2-3 times to obtain milk white spherical particles; and (3) cleaning the milk white spherical particles with vapor to obtain the resin. The prepared resin is high in stability, large in specific surface area, large in adsorption capacity, good in selectivity, rapid in adsorption speed and is capable of efficiently adsorbing gardenia yellow, and the obtained gardenia yellow is high in color value and purity; and in addition, the resin is capable of conveniently conducting regeneration treatment, long in service life and low in production cost. |
