    • PURPOSE: A gadolinium oxide measurement of content method by ICP-AES is provided to reduce a sample setup time using a small amount of sample. CONSTITUTION: A gadolinium oxide measurement of content method by ICP-AES is as follows. Gadolinium sinter is put into a pulverizing device and shatters into pieces(S1). The pulverized sample is heated and melted in acid solution(S2). Gadolinium oxide dissolving is diluted to distilled water(S3). The mass of the gadolinium element and uranium element is measured by ICP-AES in the diluted gadolinium oxide solution(S5). After the molar fraction of the gadolinium is calculated from the diluted gadolinium oxide(S6), the content of the gadolinium oxide is calculated by using the molar fraction of the gadolinium calculating(S7).
    • 目的:通过ICP-AES对含量方法的氧化钆进行测量,以减少使用少量样品的样品建立时间。 构成:通过ICP-AES对含量方法的氧化钆测定如下。 将钆烧结体放入粉碎装置中粉碎成片(S1)。 将粉碎的样品在酸性溶液中加热并熔融(S2)。 将溶解的氧化钆稀释成蒸馏水(S3)。 通过ICP-AES在稀释的氧化钆溶液中测量钆元素和铀元素的质量(S5)。 从稀释的氧化钆计算出钆的摩尔分数(S6)后,通过使用钆计算的摩尔分数来计算钆氧化物的含量(S7)。
