一般描述

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.

应用

  • Diaion WA30 was used for pre-conditioning the columns for HPLC analysis.
  • Diaion WA30 was used for immobilization of enzymes.
弱碱性阴离子交换树脂,是处理高分子量有机酸的最佳选择。它也有很强的脱色能力。该树脂的应用范围包括:水处理,玉米糖浆、甜菜糖和葡萄糖的预处理,福尔马林、甘油和酶类的精炼,以及用作弱碱性催化剂。该树脂符合美国食品药品管理局食品添加剂法规 21 CFR 173.25 的要求。
