Fresh water is a finite resource vulnerable to contamination.

Researchers from the University of Guelph (U of G) and scientists from the Canadian Light Source (CLS) at the University of Saskatchewan (USask) are developing low-energy strategies to purify .

"We've been looking at the purification of surface water, groundwater and wastewater," says Erica Pensini, Associate Professor in the School of Engineering at U of G. "We found that it was possible to use molecules that are both water-loving and oil-loving to separate solvents from water."

The team used the Mid-IR and Brockhouse beamlines to investigate the efficacy of their technique and visualize the ways the molecules interact. Their findings were recently published in Physics of Fluids.
