Sustainable Bifunctional ZnO Composites For Synchronous Adsorption And Reduction Of Cr(VI) to Cr(III).

In decentralized systems, adsorption-based strategies offer inherent advantages for the treatment of drinking water contaminated with oxoanion. However, these strategies only involve phase transfer and not the transformation to an innocuous state. The requirement for an after-treatment procedure to manage the hazardous adsorbent further complicates the process.
