So I am performing a relatively simple coprecipitation experiment to synthesize ceramics. All my precursors are in aqueous solutions. But due to the high surface tension of water, drying the water is affecting my surface area and porosity. So I have introduced a solvent washing step, where I try to replace water by ethanol using ethanol washing, as the surface tension of ethanol is quite low. So I am hoping that when I replace water by ethanol, the morphology of my particles will be improved.
I need to measure how much water has been effectively replaced by ethanol.CHN analysis is one way to it, but we don't have that in our lab.
Is there any other relatively simple way in which I can do this?
Thanks for assisting
