Protection of the aquatic environment from harmful substances is one of the urgent problems of our time. Water bodies of large industrial centers of the country are constantly polluted by dumps containing compounds, ions of copper, zinc, chromium, nickel, for which a number of methods are used. To purify wastewater from harmful substances, among which sorbent processes have gained great importance.

Selective fibrous sorbents of chromium (6+) and copper with high exchange capacity and satisfactory chemical resistance were developed. An economic agreement (contract) for the supply of a batch of sorbent was concluded with Ecopolymer Company.
