Decolorization of Limonium bicolor kunze (Bge.) Polysaccharides by Resins

Abstract:

To select a suitable decolorizing resin for Limonium bicolor Kunze (Bge.). polysaccharides (LBPs), the decolorization effect of crude LBPs by five resins are studied. And the adsorption equilibrium of LBPs pigment on the selected resin was investigated.The results show that the decolorization ratios of LX-46 is higher than those of other resins. Under optimized dynamicad sorption conditions (flow rate of 1.5BV/h, 2BV of 6mg/ml LBPS solution in 298K), the decoloration, deproteinization and polysaccharide recovery ratios of LX-46 resin were 92.08%, 92.79% and 86.53%, respectively. The above results show that macroporous anion exchange resins are suitable for the decolorization of crude LBPs.
