Abstract
Hybrid media formed by combining a metal precursor solution with particulate media to yield a mixture, decanting the mixture to yield a decanted mixture, heating the decanted mixture in via microwave radiation to yield hybrid media, rinsing the hybrid media with water, soaking the rinsed hybrid media in a salt solution, and rinsing the soaked hybrid media with water. The hybrid media includes a metal dioxide derived from the metal precursor, such as TiO2 derived from TiOSO4.
Claims14
A method of synthesizing hybrid media, the method comprising:
- combining a metal precursor solution with particulate media to yield a mixture, wherein the particulate media comprises activated carbon based media;
- decanting the mixture to yield a decanted mixture;
- heating the decanted mixture in via microwave radiation to yield hybrid media, wherein the hybrid media comprises a metal dioxide derived from the metal precursor;
- rinsing the hybrid media with water;
- soaking the rinsed hybrid media in a salt solution;
- rinsing the soaked hybrid media with water;
- and
- placing the hybrid media in contact with contaminated water comprising organic compounds, weak acid oxo-anions, or a combination thereof, wherein the hybrid media removes at least some of the organic compounds and the weak acid oxo-anions from the contaminated water.
