Abstract
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 gcm3 by using the novel method, which was higher than other similar studies. The leaching result of iodine was as low as 1.53 × 106 gm2d1 after 7 days treatment, which indicated that the solidified body has good stability in a long run.
