| 摘 要： | 研究了交联壳聚糖接枝精氨酸阴离子吸附树脂及交联壳聚糖微球吸附L-谷氨酸、β-内酰胺抗生素(青霉素G及氨苄青霉素)、尿素及Zn2+的动态吸附时间进程曲线及吸附容量。实验结果表明,交联壳聚糖接枝精氨酸阴离子吸附树脂对L-谷氨酸、青霉素G、氨苄青霉素、尿素及Zn2+的动态吸附平衡时间分别为120min、60min、75min、90min及50min,比交联壳聚糖微球分别缩短15min、15min、45min、45min、30min;对L-谷氨酸、青霉素G、氨苄青霉素、尿素及Zn2+的动态吸附容量分别是214.95mg/g干树脂、78.56mg/g干树脂、67.91mg/g干树脂、530mg/g干树脂及85.01mg/g干树脂,分别比交联壳聚糖微球提高了2.35倍、2.26倍、2.41倍、3.64倍和2.37倍。 |

| Abstract: | Crosslinked chitosan microsphere(CCTS) and its derivative grafting arginine(CCTS-Arg) were prepared for adsorption of L-glutamic acid,urea,Penicillin G,Ampicillin and Zn2+,respectively.The experiments showed that the equilibrium time for L-glutamic acid,Penicillin G,Ampicillin,Urea and Zn2+ by CCTS-Arg was 120min,60min,75min,90min and 50min,respectively,which was shorter than equilibrium time by CCTS for 15min,15min,45min,45min and 30min,respectively.The dynamic adsorption capacities for L-glutamic acid,Pen... |
