电感耦合等离子发射光谱(ICP-AES)测定白酒及浸提液中Se

Determinations of Se in white liquor and leach liquor by ICP-AES

对白酒及浸提液进行分析,为人们饮用芝麻酒提供科学依据。微波消解方法消化样品,白酒浸泡黑芝麻,浸提其中的Se元素,应用ICP-AES法测定浸提液中Se元素的含量。黑芝麻中Se的回收率为97.5%,相对标准偏差为1.45%。黑芝麻中丰富的Se元素,经过白酒的浸泡,使白酒中Se元素含量更高,与普通的白酒相比,更具有营养价值。黑芝麻酒是一种简单自制的保健酒,其药用及保健价值应引起人们的广泛关注。

Analysis white liquor and leach liquor, for people drank sesame liquor provide the scientific basis. The samples were digested in the microwave systerm, soak black sesame in white liquor, recover Se from it. ICP-AES was applied to the determination of the content of Se in leach liquor. The recovery rate of the method is 97.5% and relative standard deviation is 1.45%. We soaked the black sesame which have aburdant content of element Se in the liquor in order to increase the content of element Se. And this kind of liquor has more nutritional value compared to the ordinary liquor. Black sesame liquor is one kind of simple homemade health wine.its value of medical and health should be aroused wide attention.
