As much as a third of the world’s population does not have access to clean drinking water, according to some estimates, and half of the population could live in water-stressed areas by 2025.
As much as a third of the world’s population does not have access to clean drinking water, according to some estimates, and half of the population could live in water-stressed areas by 2025. Finding a solution to this problem could save and improve lives for millions of people, and it is a high priority among scientists and engineers around the globe.
Scientists and engineers at The University of Texas at Austin have created a hydrogel tablet that can rapidly purify contaminated water. One tablet can disinfect a liter of river water and make it suitable for drinking in an hour or less.
“Our multifunctional hydrogel can make a big difference in mitigating global water scarcity because it is easy to use, highly efficient and potentially scalable up to mass production,” said Guihua Yu, an associate professor in the Cockrell School of Engineering’s Walker Department of Mechanical Engineering and Texas Materials Institute.
Yu and his team recently published their findings in the journal Advanced Materials.
