摘要
报导用超滤法浓缩胎盘萃取液的试验研究。本法与传统的硫酸铵盐析法和冻干法浓缩相比,具有工艺简单、设备投资少、能耗低、收率高等优势。试验对影响超滤渗透通量及截留率的主要参数进行了实验研究,从而为实际应用提供了基础数据。
The condensation of extractive liquid of placenta by ultrafiltration is studied. Compared with methods such as NH4SO4 salting out and freezing drying, this method is of simple technology, low investment, low energy consumption and high yield. The factors that affect the permeation flux and entrapment rate are studied in detail.
