Synthesis and characterization of a spinel doubleoxide nanopowder and phosphate removal study from aqueous media

In this research a spinel type double oxide nanopowder LiMn0.5Co1.5O4 was prepared by sol-gel method and its structure was identified using X-ray diffraction, thermal analysis, scanning electron microscopy and infrared spectroscopy methods. The X-ray diffraction pattern (XRD) showed that after the calcination, only the pericardial phase with spinel structure was formed. After identification and characterization of synthesized spinel, phosphate removal process was investigated. In this process, various parameters such as time, adsorption concentration, dye concentration and pH were studied.
