摘要
Some macroreticular adsorption resins were used for decolorization of vitamin B6 in aqueous solution. The results show that the resins with higher specific surface have a higher decolorizing efficiency. The decolorizing process of resin AB 8 was more rapid. Resin H103 had high decolorizing efficiency, but wasnt easily regenerated. Treatment of crude Vitamin B6 solution by adsorbent ToH allows for multiple regeneration cycles without loss of decolorization properties. The decolorization of the crude Vitamin B6 was 85%.
