有机滤头和水系滤头，如何选用？

韩非子1

滤过时如何选择滤头？是不是看溶剂是有机？还是水？

看那个占的比例大，就用那个

对，主要看那个成份比例大的。

按照下文理解，亲水性的滤膜/滤器是广泛使用在制药行业的工艺过滤（水，有机溶剂，水和有机的混合体），其主要是用于除杂（因为水分子浸入滤膜孔道，起到组织杂质通过）；而疏水性滤膜/滤器主要是用于除水（用于其材质的疏水性），仅供参考！关于选自滤头，除了考虑疏水，亲水外，参见PRINCIPLES OF FILTRATION | STERLITECH CORPORATION

HYDROPHILIC AND HYDROPHOBIC
One of the important characteristics in membrane selection is whether you want a membrane that is Hydrophobic or Hydrophilic. Here we'll define these terms, as well as provide some examples of membrane materials and applications for both types.


Hydrophilic literally means “water loving.” Hydrophilic membranes will attract water, and in the process push away other molecules in order to allow water access to the membrane. This keeps contaminants away from the membrane allowing it stay clean and functioning for a longer period of time. Because of this trait hydrophilic membranes are especially well suited for medical applications and biological assays.


Hydrophobic on the other hand, literally means “afraid of water.” These membranes will block the passage of water and are commonly used for applications involving separation of water from other materials, such as venting gases.


Here is a helpful table that compares membrane materials and common uses for hydrophilic and hydrophobic properties:

还是看水和有机成分的多少吧！

一般有机用的多

主要看你用的溶剂 有机溶剂多用有机的

fyi,补充一下，原来可能不完全：

其实直接选有机的就行了，基本溶液都可以过
