摘要
利用JK006阳离子交换树脂从酶转化液中分离提取L-苯丙氨酸,对吸附、除杂、洗脱再生等工艺进行研究.吸附损失率几乎为零,对L-苯丙氨酸的吸附量达到97.5 g·kg-1湿树脂,L-苯丙氨酸洗脱收率达到94.5%,洗脱液浓度达到28～30 g·L-,并对洗脱尾流和再生洗涤水进行了再利用,降低了成本,减少了污染.
Separation of L - phenylalaning by cation exchanged resin JK006 was studied, including adsorption, scrubbing, desorption and regeneration. The loss of adsorption is very low while 94.5% of L - phenlalaine was ob- tained by desorption, and the concentration can reach 28 ～ 30 g · L^-1. Wake flow of desorption and washing of regeneration were reused to reduce the cost and pollution.
