How can I detect polyethylene glycol (PEG) concentration in a Polyethylene Glycol and Ethanol Solution?

31 January 2020 1 4K Report

In PEG+ Ethanol solution after membrane separation by which techniques we can determine ppm concentration in permeate and retentate solution?

Sanjay Chaudhri

Dear Naveed,

Simple method is to remove the ethanol in rota-vapor. PEG was not evaporated so you will get PEG after rota-vapor. By measuring weight of either ethanol or PEG, you can calculate the ppm.

Regards,

Sanjay
