Tannins are large molecular weight organic compounds. They are formed through the decomposition of plants and, to a much lesser degree, animals. These organics are generally found in surface waters or shallow wells. There are two primary categories in which tannin fall: Humic acid and Fulvic acid . These are simplified structures of very large molecules.
If you need resin for tannin removal, welcome to contact with Lanlang ion exchange resin factory.
Lanlang TA213D is special used for tannin removal.
Please check the following product specification;
Lanlang ® TA213D
Macroporous type I strong base anion exchange resin
Used for tannin removal, organic scavenger, sugar decolorization.
Lanlang ® TA213D Is a premium grade macroporous type I strong base anion exchange resin with polyacrylic matrix and quaternary amine (Trimethylamine) function group in standard Gaussian size distribution. Its macroporous structure makes it can adsorb soluble organic molecules and provides good performance to resist to osmotic & mechanical shock and oxidation. The acrylic structure makes TA213D has excellent desorption of organics during regeneration. TA213D is used in multi bed demineralization to prevent resins from organic fouling. It (or combining with TA201D) also could be used for sugar decolorization.
Water demineralization (deionization), organic scavenger, sugar decolorization.
Polymer matrix structure:
Macroporous polyacrylic crosslinked with divinylbenzene (DVB)
White opaque, spherical beads
Quaternary amine type I (Trimethylamine)
