Renewable Solar Energy Could Purify Water, New Study Shows
A new study from the University of Illinois Urbana-Champaign suggests that renewable solar energy could play a crucial role in purifying water.
Traditionally, electrochemical separation has been employed for water remediation, an energy-efficient method for purifying contaminated water. However, this process typically relies on electric energy derived from nonrenewable sources, such as fossil fuels.
Using Solar Energy for Purifying Water
A team of chemists at the University of Illinois Urbana-Champaign has made a breakthrough by integrating solar energy into the electrochemical separation process using a semiconductor.
This approach harnesses solar power to drive a redox reaction, manipulating ions’ electric charge to effectively separate them from water solutions.
In a demonstration of this system, the researchers effectively separated and removed dilute arsenate, a byproduct of arsenic from steel and mining industries, from wastewater. This development holds promise for the water treatment and environmental protection industries.
