摘要
文章主要研究模拟高放废液加入沸石预处理经碱矿渣水泥固化后Cs+的浸出性能。实验结果表明,处理含Cs+高放废液固化体中加入沸石,能使Cs+浸出率降低";两步法"掺入沸石固化体抗Cs+浸出性能更有所提高;pH值升高Cs+的吸附比增大。
Simulated high level liquid waste was pretreated with zeolite as additive. After the solidification of alkali activated slag cement, Cs^＋ leaching rate was studied. Results revealed that zeolite as additive in simulated high level liquid waste reduced Cs^＋ leaching rate, and the resistance of Cs^＋ leaching increased after zeolite was added in two-step method. Adsorptive capacity increased when pH value increased. The study was useful to enhance efficiency of treatment of high level liquid waste.
