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-Fe₂O₃-MoS₂ composite
was prepared and characterized were made via FT-IR and XRD. The XRD powder pattern of the composite showed that it
contained g-Fe₂O₃ (PDF card
no:00-002-1047), MgAl(OH)14.XH₂O (PDF card no:00-043-0072) and MoS₂
(PDF card no:00-037-4492). Thermal stability of the composite was investigated
via DTA/TG technique. MgAlOH-ɣ-Fe₂O₃-MoS₂
composite was shows highly efficient sorption for vegetable oil up to 418%
times its own weight. The ablity of MgAlOH- ɣ-Fe₂O₃-MoS₂
composite for removing Pb²⁺ ions from aqueous solution. Pb²⁺
analysis was made by ICP-OES. The effect of Pb²⁺ amounts, PH, sorbent
amounts and solvent flow rate on the adsorption capacity of MgAlOH-
ɣ-Fe₂O₃-MoS₂
composite were also ivestigated.
