					</table><p>Chemists at the <a href="https://illinois.edu/" target="_blank" rel="noopener">University of Illinois Urbana-Champaign</a> have taken a significant step towards a greener future for water remediation, where they have demonstrated the integration of solar energy into an electrochemical separation process.</p>
<p>The researchers said the discovery opens doors to potentially power such applications entirely with renewable energy sources.</p>
<p>Electrochemical separation, or electrochemical desalination, is a promising technique for purifying contaminated water and environmental remediation.</p>
<p>This energy-efficient strategy has shown potential in addressing water pollution challenges by utilizing electricity to manipulate ions&#8217; electric charge and separate different particles within a solution.</p>
<p>However, the conventional reliance on non-renewable energy sources, such as fossil fuels, has raised concerns about the long-term sustainability of electrochemical processes.</p>
<p>The research team has pioneered a novel approach to power electrochemical separation using renewable energy sources, specifically solar energy.</p>
<p>Using a semiconductor, the researchers harnessed solar energy and integrated it into the electrochemical separation process, traditionally powered by a redox reaction.</p>
<p>This advancement allows for manipulating ions&#8217; electric charge within a solution, facilitating the effective separation of particles, such as dilute arsenate derived from industrial waste from wastewater.</p>
<p><strong>Sustainable Water Remediation</strong></p>
<p>One of the prominent waste components in wastewater is dilute arsenate, a derivative of arsenic, originating primarily from steel and mining industries. This toxic element poses significant environmental risks, necessitating efficient removal techniques.</p>
<p>The researchers&#8217; proof-of-concept study showcased the successful separation and removal of dilute arsenate from water using their solar-powered electrochemical separation system.</p>
<p>The energy-efficient nature of electrochemical separation, coupled with the use of renewable energy, can lead to cost reductions in water remediation processes.</p>
<p>In February, researchers from the Massachusetts Institute of Technology (MIT) <a href="https://www.mercomindia.com/mit-remove-carbon-dioxide-from-seawater" target="_blank" rel="noopener">said</a> they had discovered the key to removing carbon dioxide directly from ocean water, which absorbs 30-40% of carbon emissions prevailing in the atmosphere.</p>
<p>A recent study by Texas A&amp;M University researchers <a href="https://www.mercomindia.com/researchers-potential-in-water-based-batteries" target="_blank" rel="noopener">revealed</a> that the storage capacity of metal-free, water-based batteries can vary a 1,000% depending on the electrodes used.</p>
