We prepared Quantum dots in ethylene glycol (EG) medium. we wish to prepare Quantum dots modified glassy carbon electrode but the problem is the removal of ethylene glycol because it won't dry/evaporate. Is any other possible way to convert the QDs to water from EG. Kindly give your valuable suggestions and comments.
Thanks in advance.
Need to use organic solvent to wash, as ethanol to wash
Centrifuge. Rinse the precipitate with ethyl alcohol. Centrifuge. The precipitate is dried and dispersed in water with the addition of one monomolecular layer of sodium dodecyl sulfate.
Thank you for all of your comments. If I use ethanol, is the solution containing the dispersion of QDs in ethanol? Apart from this is it necessary to dialysis this solution or not?
You can prefer dialysis to attain QDs purity and monodispersity in size.
you can use adsorption techniques such as activated carbons powder to remove ethylene glycol by stir
