对于成分复杂,既含有玻璃骨架元素,又含有高放废液组分,容器腐蚀产物等19个元素的玻璃固化模拟体的溶样方法进行了研究。采用偏硼酸锂熔融法可以把样品溶解完全。由于玻璃具有大分子型无序的非晶体结构,两倍于样品的熔剂量足以分解玻璃固化体。熔剂量的减少有利于排除雾化器的堵塞,并可降低对熔剂纯度的要求;利用王水-氢氟酸强大的分解能力在市售的以PTFE薄膜保持密封的聚乙烯瓶内(低压密封)可
The solution method of the glass-cured mimetibody containing 19 elements including the glass skeleton element, the component of high-level liquid waste, and the corrosion products of the container was also studied. Using lithium metaborate melting method can dissolve the sample completely. Since the glass has a macromolecular disordered amorphous structure, twice the amount of flux of the sample is sufficient to decompose the glass cured body. Reducing the amount of flux helps to eliminate clogging of the nebulizer and reduce the need for flux purity. Utilizing aqua regia, the strong decomposition capacity is found in commercially available polyethylene bottles held in a sealed PTFE film (low pressure seal )can
