How to wash an hydrogel of lignin and PEGDGE?

27 August 2024 1 9K Report

Hi there!

Im working with hydrogels of agave lignin crosslinked with PEGDGE in alkali media but i need to wash them to quit the excess of reagents, when i wash them on water they swell and lose its structure, i tried on acid but the salt formation seems to be dehydrating the gels causing hornification, in which media could i wash my materials?

Thank you!
