Scientists at UC Riverside created a new catalyst that breaks down perchlorate in water. This could help reduce hazardous waste and make it easier to clean contaminated water.
For decades, water treatment plants have used big tanks with special beads to remove perchlorate from drinking water. Perchlorate is a chemical used in rocket propellants and other industrial materials that can harm people's health if ingested.
But these beads get loaded with perchlorate and need to be either regenerated or thrown away as hazardous waste. Now, researchers at the University of California, Riverside (UCR) have developed a new way to break down perchlorate using tiny ruthenium nanoparticles. These particles are enhanced with an organic compound that helps them work quickly at room temperature.
The team led by Jinyong Liu, associate professor of chemical and environmental engineering at UCR, tested their catalyst on high concentrations of perchlorate. They found it could convert perchlorate into harmless chloride, the same ion found in table salt. This breakthrough study was published in the journal ACS Central Science.
The new catalyst is significant because it can work in water with other common contaminants like nitrate. Previous catalysts would be deactivated by nitrate, requiring extra steps to treat the water.
Why It Matters
This discovery could help India's drinking water treatment plants reduce hazardous waste and make it easier to clean contaminated water. Perchlorate is a major pollutant in many industrial areas around the world, including India.
