摘要
为解决放射性土壤去污处理问题,利用等离子体高温熔融的方法对含模拟放射性核素污染的土壤进行了玻璃固化处理,并同时研究放废土壤经等离子体高温熔融后形成玻璃体的性能。结论显示,经高温熔融后,模拟核素能够稳定存在于所形成的玻璃样品中,XRD和Raman光谱均未观察到核素的晶态和结构变化。实验表明,相对于传统的处理含模拟放射性核素污染土壤的固化方法,高温熔融处理放射性土壤废物是一种具有潜在应用价值的处理技术。
To solve the problem of management of radioactive earth,high temperature melting method with plasma was utilised to solidify the radioactive earth into glass form and study the performance of this glass after vitrification.The result shows that,after high temperature transformation,the simulated radioactive earth is formed into well distributed glass after plasma melting.The results shows,after high temperature melting,the simulated radioactive nuclides stay stably inside the glass sample,XRD and Raman reveals that no obvious signal of simulated radioactive nuclides were detected.In summary,the glass vitrification method of radioactive earth with high temperature by plasma is a potential method with good application.
