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

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.
