There's nothing more essential than clean water... and Korean researchers have found an easier and quicker way to purify water.<br />Park Se-young has more.<br />This wastewater contains phenol, a toxic chemical compound.<br />Passing electricity through a catalyst purifies the wastewater …at a rate of one liter every ten hours.<br />The researchers chose to use a new material for their catalyst - nickel.<br />The production cost is similar to that of other metal-based catalysts, but it is nine times more efficient at purifying water.<br /><br />"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."<br /><br />Purifying one liter of water requires about one gram of catalyst, …which can be used repeatedly, and doesn't create any harmful byproducts.<br />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.<br />Park Se-young, Arirang News.<br />
