[Abstract] Total Se content in rice is normally low and it is difficult to determine it exactly because of Se volatilization and pollution during the digestion process. In this method, rice sample is digested thoroughly and Se volatilization is reduced greatly by designing a specific digestion tube, increasing digestion temperature by three steps, controlling the amount of mixed acid and adjusting the location of digestion tube in the digestion furnace. Se pollution is also reduced greatly by specific cleaning treatments.
[摘要] 水稻总硒含量通常较低，很难准确地确定它是由于在蒸煮过程中的Se挥发和污染。 在该方法中，通过设计特定的消化管，提高消化温度三个步骤，控制混合酸的量和调节消化管在消化炉中的位置，大大消化大米样品并且大大减少Se的挥发。 由于特定的清洁处理，Se污染也大大减少
