| titleOfInvention | Method for preparing simulated pollucite source core by soaking |
| abstract | A method for preparing a simulated pollucite source core by soaking, belonging to the technical field of nuclear waste industrial treatment. The invention adopts a modified aluminum-silicon molecular sieve as a base, adds a small amount of graphite, presses and forms, soaks and adsorbs Cs, and then calcines and forms. The method comprises the step of using HNO 3 Solution processing of the aluminum-silicon molecular sieve; taking graphite as a lubricant, mixing the graphite accounting for 5-10% of the aluminum-silicon molecular sieve by mass percent, and performing compression molding under 3-8 MPa; then calcining for 2-4 hours at 500-700 ℃ in air atmosphere; adopting a mode of soaking to adsorb Cs, standing for adsorption, taking out and drying; then the temperature is raised to 1000 ℃ at the speed of 10-15 ℃/min, and the temperature is kept for 2-4 hours. The invention avoids solidifying Cs under high temperature, solves the volatilization problem of Cs, ensures the safety and operability of experiment under radiation condition, and is especially suitable for preparing radioactive source core. |
