Abstract
A method of measuring a gadolinia content using inductively coupled plasma-atomic emission spectrometry is provided. The method can include grinding sintered gadolinium using a percussion mortar to obtain a ground sample; warming the ground sample and then dissolving it with an acid solution to obtain dissolved gadolinia; diluting the dissolved gadolinia with distilled water to obtain a diluted gadolinia solution; measuring mass of each of a uranium element and a gadolinium element in the diluted gadolinia solution by a unit of ppm using the inductively coupled plasma-atomic emission spectrometry; and calculating a molar fraction of gadolinium from the diluted gadolinia solution and then calculating the gadolinia content using the molar fraction of gadolinium.
