[1D08] Molecular size distribution of gamma-ray irradiated humic acid complexed with metal ions

*Qi Zhao1, Takeshi Saito1, Taishi Kobayashi1, Takayuki Sasaki1 (1. Kyoto Univ.)

Keywords:Humic acid, Gamma-ray irradiation, Size distribution, Complexation

This study aims to assess the physicochemical difference of humic acid fractions (<10, 10-50, 50-100, >100 kDa) induced by Co-60 gamma-ray irradiation up to 100 kGy, and investigate its impact on the metal complexation ability.
