Physicochemistry of concentration mechanism of radioactive elements into zeolite and

粘土矿物和沸石矿物通常被认为是高吸收或吸收效应的一般特征。确切地说，离子和离子被集中在矿物上，由晶体晶格和吸收或吸收作用对矿物颗粒表面的吸收效应结合在一起。在目前的研究中，一些开始的骨质疏松玻璃被试验在200℃的温度和15.3兆帕的蒸汽压力下进行了治疗，在特定情况下，玻璃稳定元素如Sr、Cs、Li和B在Delail下进行了研究，并对化学行为和在当前实验中的分布进行了研究。目前的研究方案已被确定为可用于对高水平放射性废物的地质处置的评估。使用系统Na-Cs-Sr-B-Li-Si-Al-O的硼硅玻璃。实验性研究已被证明是由富含骨质疏松玻璃的羟基治疗进行的。代表性矿物。 ... More species obtained in experiments is analcime （NaAlSi206 · nH2O） belonging to zeolite group。analcime通常由Cs元素替代，其中Cs承载和不含钠的物种被命名为pollucite （CsAlSi 2 O 6）。污染物是由H20在其晶体中的显著特征化的，化学反应速率趋向于减少与Analcime浓度的增加。在对比中， B和Li明显贡献了Analcime水晶化的进展。The lattice parameter of analcime depends on amounts of Si of 48 g site of the cr0， while the parameter doesn't necessarily depend on the contents of alkali or alkali earth elements。如何从锂轴承的硼硅玻璃中形成一种模拟效果显示出晶格属性的特性比一种来自锂纤维硅玻璃的特性大。Considering the charge balance of the crystal Li has to occupy the crystallographic lattice。由不含Sr-free Borosilicate玻璃制成的模拟剂，由不含B含Borosilicate玻璃制成的模拟剂含有小Sr.它被结合成这样，即持有Sr-free Borosilicate玻璃的形成应该需要的麻醉剂B。Less（低）

Clay and zeolite minerals are usually characterized by considerably high adsorption or absorption effect of ions. Exactly, ions and anions are concentrated into mineral by substitution of crystallographic lattice and adsorption or absorption effect on the surface of mineral grains. In the present study some starting borosilicate glasses have been treated experimentally under the hydrothermal condition of a temperature of 200℃ and a vapor pressure of 15.3MPa In particular, the glass constituent elements such as Sr, Cs, Li and B have been examined in derail with respect to chemical behavior and distribution within zeolite formed in the present experiments. The present study program was established in order to apply for the assessment of geological disposal of high-level radioactive wastes. The starting borosilicate glasses consist of the system Na-Cs-Sr-B-Li-Si-Al-O. Experimental study has been performed by hydrothermal treatment of powdered borosilicate glass. The representative mineral … More species obtained in experiments is analcime (NaAlSi206 ・ nH2O) belonging to zeolite group. Na lattice of analcime is substituted usually by Cs element The Cs-bearing and Na-free species is named as pollucite (CsAlSi2O6). Pollucite is characterized by a deficient of H20 within its crystal In addition, the chemical reaction rate tends to decrease with the increase of Cs concentration of analcime. On the contrary, B and Li contribute obviously to progress in crystallization of analcime. The lattice parameter of analcime depends on amounts of Si of 48g site of the crystal, while the parameter doesn't necessarily depend on the contents of alkali or alkali earth elements. However the analcime formed from Li-bearing boroeilicate glass shows the feature of lattice properties larger than the one from Li-free borosilicate glass. Considering the charge balance of the crystal Li has to occupy the crystallographic lattice. The analcime formed from Sr-free borosilicate glass scarcely includes B, and the analcime formed from B-free borosilicate glass contains little Sr. It is concluded that the formation of Sr-bearing analcime should need necessarily B.
