两性离子交换纤维

强酸弱碱型两性离子交换纤维的制备I.苯乙烯和4-乙烯基吡啶的接枝共聚

STUDIES ON THE PREPARATION OF STRONG ACIDIC-WEAK BASIC AMPHOTERIC ION EXCHANGE FIBER I. the grafting copolymerization of styrene and 4-vinylpyridine onto polypropylene fiber

两性离子交换纤维还具有洗脱容易，洗脱液用量少的特点。

The amino acids on amphoteric ion exchange fiber are easy to be eluted and a small amount of elution reagent is therefor needed .

结果表明在相同分离操作条件下，所制备的阳离子交换纤维PP-g-St-SO3H和两性离子交换纤维PP-g-4VP-SO3H对混合氨基酸的分离性能比通用732树脂好。

The experimental results show that PP-g-St-SO_3H and PP-g-4VP-SO_3H have a higher separation efficiency than general used 732 ~ # resin for the separation of amino acids mixtures under the same separation conditions .

对新研制的强酸型离子交换纤维PP-g-St-SO3H和两性离子交换纤维PP-g-4VP-SO3H分离混合氨基酸的性能进行研究，并与相应的离子交换树脂进行比较。

The separation properties of amino acids mixtures on the new products of strong acid ion exchange fiber PP-g-St-SO_3H and amphoteric ion exchange fiber PP-g-4VP-SO_3H prepared by us were investigated and compared with that on relative ion exchange resin .
