想请教下离心洗涤制备出的Ag@Fe2O3-GO纳米复合材料时用乙醇和异丙醇区别
|
|
如题，之前看的大部分文献上都写的用去离子水和无水乙醇洗涤，但是有篇文献上是"The as obtained Ag@Fe2O3-GO NCs were washed with isopropyl alcohol (IPA) for three times to remove impurities, which were then redispersed in water",不知道有什么区别吗？而且这个的意思是用异丙醇洗涤三次后就直接分散在水里吗？不需要再用水洗涤一下吗？那样不会还有异丙醇残留在复合材料的水分散液里吗？ 希望大家能够指点一下，真的非常感谢！ |
