Lewatit®S 5428是一种基于交联聚丙烯酸酯的食品级大孔强碱性（I型）阴离子交换树脂。它是珠状的，具有特殊的珠尺寸分布，可用于以下过程：并流系统逆流系统（Lewatit®•WS系统/流化床）逆流系统（Lewatit®•VWS系统/复合流化床）在其氯化物形式中，Lewatit®S 5428适用于糖的生产中的糖浆脱色，特别是有机产品的甘蔗糖溶液， G。甘油，氨基酸Lewatit®S 5428的大孔结构和平衡树脂基质促进了吸附和解吸的动力学。吸附的物质， G。来自糖溶液的高分子亲水性阴离子有机物质和着色剂，可以通过中性或碱性氯化钠溶液再生而轻松解吸。因此，强烈建议Lewatit®S 5428在需要完全和快速去除相对高浓度有机物质的地方使用。与其他Lewatit®吸附剂树脂（如Lewatit®S 6368 A）一起使用可以同时进行精细抛光。如果使用Lewatit®S 5428处理饮用水和上述水溶液，应特别注意新树脂的初始循环。请参考推荐的启动条件。

Lewatit® S 5428 is a food grade, macroporous, strongly basic (type I) anion exchange resin based on a

crosslinked polyacrylate. It is bead-shaped and has a special bead size distribution for use in the following

processes:

• Co-current system
• Counter-current systems (Lewatit® • WS system / fluidized bed)
• Counter-current systems (Lewatit® • VWS system / compound fluidized bed)

In its chloride form, the Lewatit® S 5428 is suitable for the decolorization of:

• syrups from sugar production, especially cane sugar
• solutions of organic products, e. g. glycerin, amino acids

The macroporous structure and balanced resin matrix of Lewatit® S 5428 facilitate the kinetics of adsorption

and desorption. Substances adsorbed, e. g. high-molecular hydrophilic anionic organic substances and

colorants from sugar solutions, can be desorbed easily by regeneration with a neutral or alkaline sodium

chloride solution.

Lewatit® S 5428 is therefore highly recommended for use wherever complete and rapid removal of a

relatively high concentration of organic substances is required. Use in combination with other Lewatit®

adsorber resins such as Lewatit® S 6368 A allows simultaneous fine polishing.

If using Lewatit® S 5428 to treat potable water and the aqueous solutions listed above, special care should

be given to the initial cycles of the new resin. Please refer to the recommended start-up conditions available

on request.
