【Abstract】 The methods and conditions of adsorbing and desorption radish pigment were studied. The results show that the X 5 Macro porous resin has good adsorbing ability for radish pigment. The adsorbing ability is affected by temperature and acidity. The higher the temperature, the faster the adsorbing. This resin has a high adsorbing ability for radish pigment when the acidity is about pH=3.0. The concentration of alcohol has an effect on desorption. When the concentration is about 70%, the result of desorption is good.更多还原
