This product is type of macroporous anion type decolorization special resin which is prepared by the copolymer made by St-DVB and porogenic agent through suspension and polymerization after porogenic agent being extracted.Due to its macroporous net structure,special aperture distribution and weak exchange groups,this product is extensively applicable for pigment eluting in organic fermentation solution and decolorizing of starch sugar.

Under the proper application and store condition,this product shall have good stability that can not be dissolved in the water as well as the normal acid,alkali and standard organic solution.

Properties:good mechanical strength,long service life,homogenous and retional aperture distribution; strong organic stain resistance;exccellent eluting power and fast regeneration rate.

This product is especially applicable for eluting organic,gel-type weak anion contained pigments from biological fermentation solution and food,such as MSG Neutralizer.It's also extensively applicable for the decolorization of ammo acid,and the extraction of organic pigments during starch sugar production
