LDH- ɣ-Fe2O3-MoS2 composite for Vegetable Oil and Pb2+ Removal From Water

Abstract

Water pollution is a global concern. Inorganic and organic pollutants constitute primary pollutants in water resources. Therefore, it is of great concern to develop advanced sorbent materials for effective and efficient removal of metals and oil from water. In this study, synthesis of new LDH composites which would be used for sorption of heavy metals and oils from polluted water. For this purpose, MgAlOH- ɣ -Fe 2 O 3 -MoS 2 composite was prepared and characterized were made via FT-IR and XRD. The XRD powder pattern of the composite showed that it contained g -Fe 2 O 3 (PDF card no:00-002-1047), MgAl(OH)14.XH 2 O (PDF card no:00-043-0072) and MoS 2 (PDF card no:00-037-4492). Thermal stability of the composite was investigated via DTA/TG technique. MgAlOH- ɣ -Fe 2 O 3 -MoS 2 composite was shows highly efficient sorption for vegetable oil up to 418% times its own weight. The ablity of MgAlOH- ɣ -Fe 2 O 3 -MoS 2 composite for removing Pb 2+ ions from aqueous solution. Pb 2+ analysis was made by ICP-OES. The effect of Pb 2+ amounts, PH, sorbent amounts and solvent flow rate on t he adsorption capacity of MgAlOH- ɣ -Fe 2 O 3 -MoS 2 composite were also ivestigated.
