摘要：

Samples of a composite sorption material based on a highly porous polyurethane foam matrix with various pore sizes were obtained. Activated charcoal powder of different size range, impregnated with TEDA, was deposited on the matrices. During the tests, high capture efficiency of radioactive methyliodide was achieved, not inferior to the capture efficiency of a layer of industrial granular sorbent with significantly lower hydraulic resistance compared to the latter.
