Radiolysis of 2,3,7,8-tetrachlorodibenzo-p-dioxin in aqueous solutions

The conversion of 2,3,7,8-tetrachlorodibenzo- p -dioxin (TCDD) in diluted aqueous solutions at different absorbed doses of ionizing radiation using the 60 Co source is studied. The radiochemical yield of TCDD conversion is (0.3–1.5) × 10 −5 molecules/100 eV for solutions with 0.2–2 μg/L TCDD in open...

Description
Summary:The conversion of 2,3,7,8-tetrachlorodibenzo- p -dioxin (TCDD) in diluted aqueous solutions at different absorbed doses of ionizing radiation using the 60 Co source is studied. The radiochemical yield of TCDD conversion is (0.3–1.5) × 10 −5 molecules/100 eV for solutions with 0.2–2 μg/L TCDD in open cells and 2.4 × 10 −5 molecules/100 eV for air-sparged 2 μg/L TCDD solutions. It is demonstrated that the absorbed dose of ionizing radiation (25 kGy) lowers the TCDD concentration in oxygen-containing aqueous solutions virtually to zero.
