Africa-Press – South-Africa. <\/strong><\/span>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.<\/p>\n

Developed as part of an international team, the material makes it faster and easier to remove the ecotoxicant from aquatic environments.<\/p>\n

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.<\/p>\n

When filtration systems at industrial facilities fail, large quantities of lead and other metal ions \u2014 toxic to bacteria, plants and mammals \u2014 can enter wastewater or natural waters, the university specialists explained.<\/p>\n

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 \u201ccapturing\u201d lead from water in reservoirs.<\/p>\n

The material is based on humic acids extracted from coal.<\/p>\n

\u201cWe obtained lead traps with specially designed pores that can hold exactly a lead ion,\u201d said Gulnara Shigabaeva, head of the Department of Organic and Environmental Chemistry at the university.<\/p>\n

\u201cTests of the absorption process showed that the new material works more efficiently than existing analogue,\u201d she added, and \u201cthe lead can be easily removed from our sorbent.\u201d<\/p>\n

She explained that the sorbent selectively captures lead ions because it is engineered with a \u201cmemory\u201d of their size and charge \u2014 a polymer-design technique known as molecular imprinting.<\/p>\n

\u201cIn the humic-acid and acrylic-acid\u2013based material, there are cavities \u2014 imprints of lead ions,\u201d Shigabaeva said \u201cSmaller particles, such as iron ions, simply pass through them, while larger particles cannot fit into the sorbent.\u201d<\/p>\n

The granulated sorbent can be placed directly into water and later filtered out after swelling and absorbing the lead ions.<\/p>\n

Laboratory experiments showed that one gram of the sorbent can extract 50 milligrams of lead ions from water in one hour. In the future, the researchers plan to develop molecularly imprinted polymer sorbents for other ecotoxicants such as nickel, copper and zinc.<\/p>\n

They also intend to assess the effectiveness of the new materials under real environmental conditions.<\/p>\n
