Novel method for efficient solidification the iodine contained waste by B2O3–Bi2O3 glass powder at very low temperature

A novel pretreatment method was used to ameliorate the treatment effect of iodine contained radioactive waste. The pretreatment sample (15 w%) held the highest amorphous index (0.50) at 600 °C, and iodine element was in a state of uniform distribution. The density of the sample could increase to 2.95 gcm 3 by using the novel method, which was higher than other similar studies. The leaching result of iodine was as low as 1.53 × 10 6  gm 2 d 1 after 7 days treatment, which indicated that the solidified body has good stability in a long run. Graphic abstract
