Researchers at Arizona State University have developed an exciting ion-exchange media that simultaneously removes strong acids and oxo-anions from water. This media uses titanium dioxide to remove contaminants which is advantageous over the current media of iron hydroxides. Titanium dioxide is more stable and resistant to dissolution in natural waters. The fabrication process uses easy and inexpensive approaches suitable for production of large quantities of the media using very simple manufacturing processes.

Benefits and AdvantagesStability: Titanium dioxide is more stable than existing iron hydroxides used in fabricating similar media. Simultaneous: Both strong acids and oxo-anions are removed using the same media. Inexpensive: The high cost of fabrication for titanium dioxide limits the use of titanium dioxide as a media. This invention has developed an inexpensive method to synthesize the titanium dioxide. Simple: The manufacturing process is easy to develop and can produce large quantities.
