Weak Base Anion(WBA) resins are polymer made by polymerizing styrene or acrylic acid and divinylbenzene and chlorination,amination . Dongli company can provide gel and macroporous types WBA resins with different crosslink. Our WBA are available in many gradings including Cl forms, uniform size and food grade.
GA313, MA301, MA301G, MA313
Weakly basic anion exchange resin: this kind of resin contains weakly basic groups, such as primary amino group (also known as primary amino group) – NH2, secondary amino group (secondary amino group) – NHR, or tertiary amino group (tertiary amino group) – NR2. They can dissociate Oh – in water and are weakly basic. In most cases, the resin adsorbs the whole other acid molecules in the solution. It can only work under neutral or acidic conditions (such as pH 1-9). It can be regenerated with Na2CO3 and NH4OH.
