A FACILE SYNTHESIS OF POROUS HEMATITE NANOMATERIALS AND THEIR FAST SORPTION OF CR (VI) IN WASTEWATER
Porous hematite (a-Fe2O3) nanomaterials can be simply acquired from amorphous iron (III) hydroxide (Fe (OH) 3) in neutral solution by an evaporation method in an open quartz flask in a vacuum drying oven. Results show that the as-obtained a-Fe2O3 particles at 180°C for 2h or so are nearly spindle in...
