Abstract

Synthesis of membranes has been done using pillared clay FeCl₃for desalination application. Pillared clays FeCl₃were synthesized via a sol-gel method using [OH] / [Fe] 0.25, 0.5, 1, 2, 2.5. Formed sol-gel was furnace on 600^oC for 2 hours. The membranes which were cooled at room temperature for 3 days then tested filtration of seawater. The results showed that membrane pillared clays FeCl₃ with a ratio [OH] / [Fe] 0.25 reached filtration purity 99.99% with the initial TDS 27.58 ppm and resulted rejection TDS 00.22 ppm after filtration. Membrane with ratio [OH] / [Fe] 0.5 reached filtration purity 80%, with initial TDS 27.58 ppm and resulted rejection TDS 11.76 ppm, while membranes with ratio [OH] / [Fe] 1,2 and 2,5 was broken during the filtration proces, its resulted very small rejection.
