Lewatit® S 6368 A is a food grade, macroporous, monodisperse, strongly basic (type I) anion exchange resin based on a styrene-divinylbenzene copolymer. In its hydroxide form, Lewatit S 6368 A is suitable for the removal of acid and simultaneous decolorization of solutions of organic substances e.g. sugar, gelatin, glycerin, grape must, whey, fruit concentrates etc. and in its chloride form for the decolorization of sugar syrup (beet or cane), glycerin, grape must, fruit juices. The macroporous structure ensures very good adsorption of organic substances (e.g. colorants) and partial adsorption of organic acids and mineral acids. The substances are easy to be adsorbed by regeneration with caustic soda solution (OH form) or alkalized brine solution (Cl form). If using Lewatit S 6368 A to treat potable water and the aqueous solutions listed above, special care should be given to the initial cycles of the new resin.Information provided by Lanxess. |
