Hello,
I am dialyzing a solution of Carbon dots produced using ethylediamine and citric acid. Although some of them stay inside the dialysis membrane, a part of them is being released to the external solution. Is this normal? I am using a float-A-Lyzer 500-1000 Da device.
This is a problem for me, because I am creating a bias in my system (only the biggest ones will remain) and I cannot estimate a true Yield (by mass).
Thank you
Whats the ratio of volume of your sample to the liquid outside? For most dialysis kits you need to have at least 100 times more volume outside.
Jacek thank for your repply,
I am dialyzing 10mL against 2L, So that should not be a problem. But thank you for the suggestion.
Dear Rui Oliveira-Silva
Choosing a dialysis bag with suitable size is very critical. Some researcher prefer modification of qds surface to preventing of their leakage during dialysis.However, you can apply thermal methods synthesis with using furnace that does not need dialysis tubing .
Good Luck
