I am looking for a specific membrane which is alkali resistant to remove the water from the mixture of glycerol , glycerol carbonate, potassium carbonate salt and water ?
is there any pervaporation membrane or membrane distillation for this application ?
You can use PVA membrane for pervaporation process. It will separate the water from the organic mixture easily.

I am with Derya , normal pervaporation process using PVA composite membrane such as PVA/PAN will separate it easily even under moderate temperature
Dear Amir,
You can use cross-linked PVA membrane for removing glycerol , glycerol carbonate, potassium carbonate salt and water. Do not use poly(acylonitrile)[PAN] membrane in alkaline media. The -CN group of PAN will hydrolyze to -COOH in alkaline medium. PAN also degrade in highly alkaline medium.
I hope that this answer will be helful for you.
Regards,
Sanjay
PVA cross-linked with GA is also best coating layer for pervaporation.
