چکیده انگلیسی
An efficient decoloration method for polysaccharides from the sprouts of Toona sinensis (A. Juss.) Roem (PSTS) by anion exchange macroporous resins (AEMR) was investigated in the present paper. The results suggested that D941 resin offered better decoloration efficiency than other tested resins. Based on single-factor experiments, the optimal decoloration parameters of D941 resin were obtained as follows: temperature of 45 °C, sample initial concentration of 30 mg/ml, pH value of 8.5, static decoloration time of 90 min, dynamic decoloration processing volume of 5.5 BV with the flow rate of 2 BV/h. Decoloration ratio, PSTS recovery ratio and selectivity coefficient were 91.94 ± 1.23%, 90.05 ± 2.35% and 10.92 ± 0.63, respectively. Most of pigment impurities were successfully removed from PSTS solutions after treated by D941 resin, and there was no significant difference in carbohydrate concentration, characteristic groups and molecular weight. Compared with H2O2 oxidation and activated carbon adsorption, this developed method is superior.
