Russian Scientists Develop New Polymer Material to Trap Lead Ions in Water
16:35 GMT 03.12.2025 (Updated: 18:34 GMT 03.12.2025) A new material that traps lead ions in wastewater and natural waterways has been created and tested by researchers at Russia's Tyumen State University.
Developed as part of an international team, the material makes it faster and easier to remove the ecotoxicant from aquatic environments.
The results were published in
Polymer Bulletin. The main sources of heavy-metal pollution in the environment include the mining, metallurgical, electroplating and steel industries.
When filtration systems at industrial facilities fail, large quantities of lead and other metal ions — toxic to bacteria, plants and mammals — can enter wastewater or natural waters, the university specialists explained.
Researchers from the State University of Tyumen, together with colleagues from Kazakhstan, Azerbaijan, India, China and Saudi Arabia, have developed and tested a material capable of “capturing” lead from water in reservoirs.
The material is based on humic acids extracted from coal.
“We obtained lead traps with specially designed pores that can hold exactly a lead ion,” said Gulnara Shigabaeva, head of the Department of Organic and Environmental Chemistry at the university.
“Tests of the absorption process showed that the new material works more efficiently than existing analogue,” she added, and “the lead can be easily removed from our sorbent.”
She explained that the sorbent selectively captures lead ions because it is engineered with a “memory” of their size and charge — a polymer-design technique known as molecular imprinting.
“In the humic-acid and acrylic-acid–based material, there are cavities — imprints of lead ions,” Shigabaeva said “Smaller particles, such as iron ions, simply pass through them, while larger particles cannot fit into the sorbent.”
The granulated sorbent can be placed directly into water and later filtered out after swelling and absorbing the lead ions.
