摘要
目前腈纶生产过程中使用的硫氰酸钠净化工艺有吸附法、萃取法、离子交换法、离子延迟树脂法和凝胶色谱法,文章对这几种方法进行了比较,并具体介绍了凝胶色谱分离技术在腈纶溶剂回收中的应用和改进情况。
Currently, the sodium thiocyanate purification methods commonly used in production of acrylic fibers are mainly as following： adsorption, ion exchange method, ion delay resin method and gel chromatography. These methods were compared, and the applying method and effect of gel chromatography in recycle of acrylic fibers solvent were introduced in details.
