Abstract
Provided are a mineralizing removal method and apparatus for highly concentrated iodine in radioactive wastewater. According to the present invention, since only a small amount of sludge is discharged as compared to the previous treatment methods, a generation amount of the radioactive waste may be significantly decreased, such that wastewater containing highly or ultra-highly concentrated iodine may also be effectively treated. Further, only iodine may be selectively removed regardless of the presence of competitive anions in the wastewater. Treatment may be performed under a neutral or weak alkaline condition rather than an acidic condition, such that a volatilization of radioactive iodine was fundamentally blocked, and at the time of discharging the wastewater, a neutralization treatment process is not required. In addition, long term storage stability of radioactive waste may be significantly promoted by using phase-conversion of malachite and an iodine crystallization method as compared to the previous adsorption methods.
