FIELD: process engineering.
SUBSTANCE: invention relates to filtration materials with nano fibres. Proposed material comprises substrate made up of thermally bound polypropylene microfibres and effective layer consisting of 100-300 nm-dia nano fibres produced by electroforming from butyl acetate-based solution containing the mix of chlorinated polyvinyl chloride and butadiene-nitrile rubber in weight ratio of (3-10):1, respectively, with solution concentration making 10-15 wt %.
EFFECT: high-efficiency filtration material for separate measurement of alpha-active isotope content.
