Abstract:
(EN) Provided is a method for decomposing a quartz sample, including decomposing at least a portion of the quartz sample by bringing a liquid in which at least a portion of a quartz sample as an analysis object is immersed into contact with a gas generated from a mixed acid, the liquid including at least water, the mixed acid being a mixture of hydrogen fluoride and sulfuric acid, and the molar fraction of sulfuric acid in the mixed acid being in the range of 0.07-0.40.
(FR) L'invention concerne un procédé de décomposition d'un échantillon de quartz, comprenant la décomposition d'au moins une partie de l'échantillon de quartz par mise en contact d'un liquide, dans lequel au moins une partie de l'échantillon de quartz à titre d'objet d'analyse est immergée, avec un gaz généré à partir d'un acide mixte, où le liquide comprend au moins de l'eau, l'acide mixte est un mélange de fluorure d'hydrogène et d'acide sulfurique, et la fraction molaire d'acide sulfurique dans l'acide mixte est dans la plage de 0,07 à 0,40.
(JA) 分析対象の石英試料の少なくとも一部が浸漬した液体を、混酸から発生したガスと接触させることにより、上記石英試料の少なくとも一部を分解することを含み、上記液体は少なくとも水を含む液体であり、上記混酸はフッ化水素と硫酸との混酸であり、かつこの混酸における硫酸のモル分率は0.07~0.40の範囲である石英試料の分解方法が提供される。
