Abstract:

Three types of macroporous resins XDA-3, XDA-6 and XDA-7 were used for the decolorization of sugar juice concentrate. According to investigations of the effects of resin amount, adsorption temperature and adsorption time on decolorization efficiency, XDA-6 was selected for further investigations. The adsorption kinetics of XDA-6 was consistent with the equation of liquid membrane diffusion with 0.0301/min diffusion rate constant. Moreover, the adsorption isotherm also complied with the Freundlich equation.

Key words: macroporous resin, decolorization, sucrose juice concentrate, decolorization efficiency
