Leachability of Solidified Degraded Radioactive Cellulose-Based Wastes

Leachability of Solidified Degraded Radioactive Cellulose-Based Wastes

Cellulosic wastes are considered as one component of radioactive solid wastes generating during daily peaceful applications of nuclear materials. In the current article, the residual waste solution arising from the wet oxidative degradation of mixed cellulosic wastes(towel paper, filter paper and spent cotton clothes) using hydrogen peroxide as oxidant under 100°C and atmospheric pressure was solidified/stabilized through incorporation into a Portland cement matrix. Leachability as one of the most important characterizations of the final solidified radioactive waste form was evaluated to meet the final disposal requirements.
