A Breakthrough in Waste Water Purification: A Single Solution for Remediation of Five Toxic Heavy Metal Ions

Identifying the Issue

• Industrial wastewater contamination by toxic heavy metal ions (HMI) poses a significant threat to public health and environmental safety, highlighting the urgent need for effective remediation solutions.
• Existing adsorbents fail to efficiently remove diverse (both cationic and anionic) HMIs simultaneously, limiting their applicability

Objective of the Research

• Develop a singular solution for efficient remediation of five toxic heavy metal ions: Pb(II), Hg(II), As(III), As(V), Cr(VI), from water

Who should read this?
