Dear All
I prepared P25/GO 0.1 % ratio. When filtrating the solution to get the solid P25/GO 0.1 %, I found that the filterate is white as the titania pass through the filter paper. This is completely different from P25/GO 5 % ratio (the filterate is clear with no titania). Is this normal for preparation of small ratios.? I think this is not fair when comparing P25 with P25/GO 1 % ratio because a large amount of titania was not bound with GO.
I am look forward to helping me to understand this issue

By using TGA technique u can determine the amount of Go in your sample and by the way you can determine the percent of Go in each sample
One way is to increase the polyemer content and GO check and another way is : If your prepared GO is of nano size then no need to filter it, as chances adsoption of more GO (nano) particles into filtering process, The one may get less chances of exact 0.1 % of GO after filtrating the solution.
You could prepare a GO dispersion and by dryness you know the GO concentration. To that concentration determined GO dispersion add the % in mass of p25. The dispersion will precipitate and by centrifugtion you get a p25 -GO at disired concentration.
