Abstract:

Current available methods for water desalination are energy intensive, expensive, and not feasible for small-scale applications. As an alternative, hydrogels may be utilized as a draw agent and semi-permeable membrane forward osmosis by acting as both to desalinate water. This study aims to synthesize and characterize hydrogels made from cellulose derivatives and reduced graphene oxide nanofillers in order to desalinate and remove microbes from seawater without requiring a large energy input. The hydrogels are formed by combining carboxymethyl cellulose, hydroxymethyl cellulose, reduced graphene oxide, and water to form a paste which is soaked in a crosslinking solution made of citric acid. Swelling, compression, antimicrobial efficiency and desalination efficiency tests were done. The hydrogel that obtained the highest values has a swelling ratio of 1,447%, compressive strength of 4 bar, desalination efficiency of 30%, and antimicrobial properties.
