Scientists from Krasnoyarsk have created an ecosorbent for wastewater treatment

Scientists from the Krasnoyarsk Scientific Center of the Siberian Branch of the Russian Academy of Sciences have created an environmentally friendly sorbent for water purification from heavy metals. It is renewable and biodegradable, the press service of the Yenisei Siberia Development Corporation reports.

Researchers have isolated a natural biopolymer from the sawdust of Siberian spruce — galactoglucomannan, which is found in coniferous wood. Thanks to the innovative chemical treatment, the substance has acquired a high ability to attract heavy metal ions from water and hold them firmly.

The sorbent effectively absorbs lead, cadmium, copper and iron, surpassing some synthetic analogues in capacity. The novelty opens the way to the creation of new safe filters for wastewater and water treatment, writes KrasnoyarskMedia news agency.

The development is especially important for regional industrial companies, as it opens up opportunities for the introduction of effective "green" technologies using local raw materials.

Earlier, Izvestia wrote that chemists from St. Petersburg, together with their Chinese colleagues, proposed a more environmentally friendly alternative to existing water purification systems — membranes based on cellulose derivatives. With the help of the development, it is possible to purify both domestic and drinking water.

All important news is on the Izvestia channel in the MAX messenger.
