Summary

The addition of lignin to the cellulose paper improves resistance to ionizing radiation. This is possible thanks to the protective action of the aromatic compounds in the radiolysis of organic compounds. In the work described (in the entire concentration range), the protective effect of lignin sulfonate to cellulose radiolysis. Determined the efficiency of radiation emitted hydrogen and postradiation oxygen absorbed. With the use of DRS was tested effect of addition of lignin to cellulose oxidation. It is worth noticing that gas chromatography in the proposed system can be a convenient tool for assessing oxidation of polymers also in classical chemistry.
