Korean researchers develop technology to remove phenol from wastewater Updated: 2019-06-05 11:19:21 KST

This wastewater contains phenol, a toxic chemical compound.
Passing electricity through a catalyst purifies the wastewater …at a rate of one liter every ten hours.
The researchers chose to use a new material for their catalyst - nickel.
The production cost is similar to that of other metal-based catalysts, but it is nine times more efficient at purifying water.

"Phenol is known to be quite difficult to break down, but we're able to almost completely break down phenol after a ten-hour process."

Purifying one liter of water requires about one gram of catalyst, …which can be used repeatedly, and doesn't create any harmful byproducts.
Now, the researchers are looking to improve its safety by making sure that not even a small amount of the catalyst remains in the purified water.
