METHOD FOR PRODUCTION OF THIN-LAYER SORBENT BASED ON MANGANESE DIOXIDE FOR ALPHA-SPECTROMETRIC DETECTION OF RADIUM ISOTOPES Russian patent published in 2022 - IPC B01J20/06 B01J20/286 B01J20/32 G01T1/36

Abstract RU 2780727 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method for the production of a thin-layer sorbent based on manganese dioxide for alpha-spectrometric detection of alpha-radiating radium isotopes Ra-223, including exposure of film in an acidic solution of potassium permanganate, drying, characterized in that, before exposure, film is treated in a solution of sodium hydroxide at a concentration of 0.5-2 mol/dm³, and polyethylene is used as film material.

EFFECT: obtaining a thin-layer sorbent for alpha-spectrometric detection of radium isotopes.
