Seawater Desalination using Smart Polyacrylic Acid Hydrogel In Haqel-Tabuk, Kingdom of Saudi Arabia (KSA)

In the present study, we prepared polyacrylic acid h ydrogel with different concentration (10, 20, 30 mol %) of N, Nmethylene bisacrylamide (BIS) cross-linker, ammoni um peroxodisulphate (APS) and N, N, N , Ntetramethyl ethylene diamine (TEMD) the reaction proceed by free radical polymerization technique. The chemical str ucture was evaluated by infrared spectroscopy (FT-IR). The glass transition temperature (Tg) was recorded by differential scanning calorimetery (DSC). The swelling properties of hydrog els were measured in seawater, collected from the bea ch of Haql city in Tabuk kingdom of Saudi Arabia. The swelling a nd desalination of water were measured as a factor of time. In future, we are hoping to use the present hydrogel for desalination of seawater in large scale.
