摘要
本文对在我国高放废液全分离流程中产生的含铯亚铁氰化钛钾无机离子交换剂的固化进行了初步研究。结果表明，对于含铯亚铁氰化钛钾无机离子交换剂，可先用热分解－催化氧化法除去其中的氰并将其转变为各种固体氧化物，然后用由碱硬锰矿（ＢａＡｌ２Ｔｉ６Ｏ１６）、假板钛矿（ＦｅＴｉ２Ｏ５）及金红石（ＴｉＯ２）三种矿相组成的钛酸盐陶瓷固化体对其进行固化包容。制备出的陶瓷固化体性能稳定，物理稳定性和化学稳定性与硼硅酸盐玻璃固化体相当，废交换剂氧化物包容量可达３６．８％。
Immobilization feasibility for cesium loaded potassium titanium hexacyanoferrate inorganic ion exchanger generated from Chinese HLLW total separation process was studied.For the first time,the cyan in the Cs loaded K TiFC inorganic ion exchanger can be destroyed by means of thermo decomposition and catalytic oxygenolysis and the exchanger converted to some oxides at this time. Then this oxides can be immobilized and held in a titanate ceramic consisting of hollandite (BaAl 2Ti 6O 16 ),pseudobrookite(Fe 2TiO 3)and rutite (TiO 2).The property of solids produced in our work is steady. The physical and chemical stability of it corresponded to the solid of borosilicate glass. The maximum waste oxide loading is 36.8%(wt). (
