摘要
本文报道90℃下BAZ玻璃固化体在模拟粘土孔隙水(SIC)和蒸馏水中的静态浸出试验结果。试验结果表明,BAZ在蒸馏水中的质量损失(ML)为正值,在SIC中为负值;各元素的质量损失在SIC中明显低于在蒸馏水中。浸出时间为91天时,BAZ在SIC中的ML值为—1.0 g/m^2,在蒸馏水中为9.5 g/m^2。试验观察到在蒸馏水浸出液中有某些玻璃体沉积在容器底部,它们主要是由Ca、Sr和Fe组成。文中还比较了BAZ和BEL-15两种玻璃固化体在相同条件下的浸出性能。
The results of static leaching test are reported for BAZ vitrified product in simulated interstitial claywater(SIC)and distilled water(DW)at 90℃.The mass loss(ML)of BAZ was positive invalue in DW,while negative in SIC.NL of some elements in SIC was significantly lower than that inDW.At 91-th day,the ML Value in SIC was—1.0 g/m^2,and 9.5 g/m^2 in DW.Some vitrified matterconsisting mainly of Ca,Sr and Fe was observed on the bottom of vessel containing DW leachant.Acomparison between the leaching behavior of BAZ and BEL-15 vitrified products under the same con-dition was given.
