CONTENT MEASUREMENT METHOD OF GADOLINIUM(III) OXIDE

摘要

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).
