沉淀介质对合成醇Cu-Co-Fe系催化剂的影响

, 1997
分别以水和乙醇为沉淀介质，按不同方法制备了低碳醇合成用Ｃｕ－Ｃｏ－Ｆｅ系催化剂，以乙醇为沉淀介质时，有利于提高生氏碳醇的活性和选择性，产物中正构醇含量增加，且不服从Ｓｃｈｕｌｚ－Ｆｌｏｒｙ方程分布方式，乙醇的存在，使沉淀体系中的杂质ＮａＮＯ３不易洗脱，催化剂还原温度提高；高的ＮａＮＯ３含量对进一步提高催化剂的活性和选择性不利，吸附实验结果表明，乙醇预处理可提高催化剂对ＣＯ的不可逆吸附能力 ...

PEG沉淀结合层析分离重组乙肝病毒表面抗原

, 2006
应用聚乙二醇(PEG)沉淀结合层析技术纯化乙肝病毒表面抗原(HBsAg),对PEG浓度、pH值、离子强度等影响PEG沉淀的因素进行了正交实验研究.结果表明,浓度为0.12g/mL的PEG6000在4℃,pH9.0条件下沉淀HBsAg纯化效果比较理想,纯化倍数达3.7,回收率96.8%,有效地去除了生物大分子杂质和牛血清白蛋白(BSA),PEG在后续的凝胶过滤中可以除去,整个工艺的回收率可提高到41%
