Application

Diaion® WA30 free base is an anion exchange resin for high molecular weight organic acids. It has been used in conjunction with electrodialysis to remove salt and selective organic acids from salted Japanese apricot.
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.
