Abstract: In order to probe the adsorption properties and dynamics of macroporous resin on sugarcane molasses pigments,the decolorization and regeneration performance of five types of macro-porous resin on sugarcane molasses was compared using a static method. As a result,a macro-porous and ion-exchanging resin D750 was the best. The effect of resin usage,processing time,adsorption temperature and the p H of molasses on decolorization efficiency was also researched. The optimized syrup-decolorizing technology conditions of resin D750 was as follows:resin usage 10 g,processing time 6 h,adsorption temperature 60 ℃ and p H7.04.The usage,IU560 and brix of molasses was 100 m L,13500 and 12 ° Bx,respectively. Decolorization rate was86.90% under the optimized technology conditions. Further research results of adsorption performance and kinetics showed that the adsorption isotherm of D750 complied with the Freundlich equation. Moreover,the adsorption kinetics of D750 was consistent with the particle diffusion model with 0.09 min-1diffusion rate constant.
