Postradiation destruction of dextran in solutions
Description
Methods of pH-metry, UV absorption and ESR spectroscopy were used to study the oxidation destruction of dextran solutions, stored in the air after gamma irradiation (60Co) bydoses of up to 200 kGy. It is shown that polymer destruction under mentioned conditions is initiated by hydroperoxide decomposition with successive radical transformation into peroxides. Experimentally observed periodical change of acidity of irradiated dextran solutions is also explained by transformations of peroxy radicals
