| 摘 要： | 研究了聚丙烯基强碱性阴离子交换纤维对红霉素发酵液的脱色性能。考察了接触时间、pH值等因素对脱色效果的影响。结果表明，与离子交换树脂相比离子交换纤维具有脱色容量高、脱色速度快、再生速度快等优点。环境温度301K时，静态脱色30min可达到平衡，脱色率85.3%，红霉素损失率1.17%；动态脱色可提高红霉素成品的质量又不影响其收率。因此，可以将离子交换纤维应用于红霉素发酵液的脱色领域来提高红霉素产品的质量。

| Abstract: | The decoloration of the erythromycin broth by the polypropylene anion exchange fiber is studied in this paper,including the effects of contact time and pH value on decoloration characteristics.The results show that the polypropylene anion exchange fiber is better than the ion-exchange resin,with advantages such as higher exchange and rebirth speed.When the ambient temperature is 301K,the decoloration is fast,and the decoloration rate reaches 85.3% in 30 minutes,and the lose rate of erythromycin is 1.17% in ... |
