摘　　要：利用X射线荧光光谱法(XRF)测定模拟高放废液玻璃固化体的化学成分,根据模拟高放废液玻璃固化体的化学组成进行系列标准样品的制备,并对稀释比例、熔融时间和熔融温度等XRF测试条件进行探讨。结果表明,在稀释比为10:1、熔融温度为1100℃、熔融时间为20min条件下,各元素的精密度(RSD)在0.3%~4.45%之间,满足检测需求。In this paper,the chemical composition of simulated high level radioactive waste glasses is determined by X-ray fluorescence spectroscopy(XRF).A series of standard samples are prepared according to the chemical composition of simulated high level radioactive waste glasses.XRF testing conditions such as dilution ratio,melting time and melting temperature are studied.The results show that the precision(RSD)of each elements is between 0.3%and 4.45%under the conditions of dilution ratio of 10:1,melting temperature of 1100℃and melting time of 20 minutes,meeting the detection requirements.
