| 摘 要： | 利用HPD400、HPD500、HPD600、HPD700、HPD850、ADS-17、D101、DM130大孔吸附树脂对瓜果腐霉培养滤液中除草活性成分的吸附情况进行了研究,通过对树脂吸附后的流出液和洗脱液的浓缩物进行HPLC检测分析,确定了其除草活性成分。实验发现,在所选择的8种树脂中以HPD500、HPD850、HPD600、ADS-17对除草活性成分的吸附能力最强,其中以HPD500和HPD600树脂的10%的乙醇洗脱液中除草活性成分含量最高。综合结果表明,以HPD500树脂作为吸附瓜果腐霉培养滤液中除草活性成分的适宜树脂。研究发现,HPD500树脂对除草活性成分吸附和解吸附的最佳条件是:吸附最适温度为20℃,树脂吸附饱和度为33.75mL/g,较适宜吸附流速为2BV/h,较适宜脱附流速为1BV/h,洗脱剂浓度为10%乙醇,洗脱剂用量为2.5BV。

| Abstract: | In this research the herbicidal components from the fermentation broth of Pythium aphanidermatum was adsorpted by macroporous adsorption resins HPD400, HPD500, HPD600, HPD700, HPD850, ADS-17, D101 and DM130. The effluentand eluants were analyzed by HPLC and the herbicidal component was got. The herbicidal component could be adsorpted by HPD500, HPD600, HPD850, ADS-17 and the amount of herbicidal component were higher in the eluent liquids of HPD500, HPD600, so the HPD500 was suitable for adsorption of the h... |
