Descrizione generale
Diaion WA30 is highly porous weak-base anion exchange resin with tertiary amine groups. It is used as an absorbent which is effective in the removal of arsenic(V) from drinking water/ground water. It is used to separate trace amounts of Pd (II), Pt(IV) and Au(III) from macrocomponent ions.
Applicazioni
- Diaion WA30 was used for pre-conditioning the columns for HPLC analysis.
- Diaion WA30 was used for immobilization of enzymes.
Weakly basic anion exchange resin that is best in class for high MW organic acids. It also has a strong decolorization capability. Applications for the resin include: water treatment, pretreatment of corn syrup, beet sugar and dextrose, refining of formalin, glycerine, and enzymes, and as a weak base catalyst. This resin meets requirements of FDA Food Additive Regulation 21 CFR 173.25.
