Abstract
【解決手段】 大気圧より大きい圧力の酸素雰囲気下において、吸収液が注入された耐圧容器内で試料を燃焼する工程と、前記吸収液を回収し、過酸化物を添加した前記吸収液を加熱分解する工程と、加熱分解した前記吸収液を放冷する工程と、放冷した前記吸収液に還元剤を添加した混合溶液を煮沸還元する工程と、煮沸還元した前記混合溶液を放冷する工程と、放冷した前記混合溶液にマスキング剤を添加する工程と、マスキング剤を添加した前記混合溶液に含まれる不純物を除去する工程と、不純物を除去した前記混合溶液に含まれるセレンを測定する工程と、を含むセレンの定量分析方法により、試料に含まれるセレンの定量を精度よく、かつ迅速に定量することができる。
