METHOD FOR PURIFYING WATER SOLUTIONS FROM HEAVY METALS AND RADIONUCLIDES Russian patent published in 2017 - IPC C02F1/28 C02F1/44 B01D24/04 B01D71/48 C02F101/20 

FIELD: chemistry.

SUBSTANCE: method is carried out by sorption on a sorbent, using as a filter media of the track membranes. The powdered adsorbent with a particle size of 0.01-5000 microns or colloidal solution previously placed in a package of arbitrary shape, made of track membranes on the basis of polyethylene terephthalate with a thickness of 50-75 microns with a pore size of 0.01-10 microns. The sorbent occupies 5-80% of the total volume, and the edges of the end part of the package are hermetically sealed by gluing. Silica gel SiO₂, cation exchanger KU2(Na), Berlin azure are used as a powdered sorbent.

EFFECT: method provides a structurally simple and efficient technology for removing heavy metals and radionuclides.
