一般說明

Amberlite XAD-2是苯乙烯-二乙烯基苯树脂的疏水共聚物,需要较长的纯化过程,可用作吸附剂。Amberlite XAD-2 树脂,依据其疏水基团的芳香性和大小,通过低能的物理相互作用吸附有机化合物。
非离子型大网格树脂,通过疏水性和极性相互作用来完成离子吸附与解吸;通常用于等度条件下。
规格:

應用

Amberlite XAD®-2用作:
  • Soxhlat萃取技术提取有机氯化合物的吸附剂
  • 在高效液相色谱分析柱相层析提取粘附样本的吸附剂
  • 层析吸附剂
用于分子量高达 20,000 的疏水性化合物的多环芳烃吸附剂树脂,具体用途包括酚类和有机物的去除,表面活性剂、芳香化合物和抗生素的回收。可用作催化或金属去除的助剂。经整理的美国环保局版本请参见 Supelpak-2 和 Supelpak-2B。
