Purdue University researchers have developed a method to detoxify water with chlorine and ultraviolet radiation, which may provide new hope for water-stressed areas and help promote the reuse of wastewater.

The Purdue team developed a method for selectively degrading and detoxifying amines, organic compounds derived from ammonia that are common in water supplies. Amines include a number of compounds that can be toxic to humans and other animals.

Climate - Change - Populations - Changes - Water

"Climate change and increasing human populations are mandating changes in water use patterns, including water reuse and the use of water supplies that were previously identified as being of marginal or poor quality," said Ernest R. Blatchley III, a professor in Purdue's Lyles School of Civil Engineering and the Environmental and Ecological Engineering, who led the research. "As human populations increase their reliance on these water supplies, the need for effective, selective water treatment methods will increase."

The novel method developed at Purdue allows for selective degradation of amines. Pre-chlorination activates amines to subsequent UV exposure, which then promotes the degradation of...
