四、分离方法的选择 分离方法很多,在纺织助剂组成与结构剖析中,采用何种方法需要根据对样品初步观察和试验所掌握的样品的特点、来源、用途、状态、数量等线索,灵活选择应用。分离方法的选择虽无一定成规可循,但一般来说可按以下几条原则考虑。 1.样品的特性: (1)样品的亲水性、疏水性、离子型、非离子型等。大多数分离技术,或者能用于 Fourth, the separation method of choice There are many ways to separate the textile auxiliaries in the composition and structure analysis, the use of which method needs to be based on the initial observation of the sample and test the sample of the characteristics, sources, uses, status, quantity and other clues, flexible Choose Apply. Although the choice of separation method does not necessarily follow the rules, but in general can be considered according to the following principles. 1. The characteristics of the sample: (1) the sample hydrophilic, hydrophobic, ionic, non-ionic and so on. Most separation techniques, or can be used
