摘要:钠是食品中重要的矿物质,可维持机体正常的渗透压和新陈代谢,可以维持体内酸碱的平衡,对人体
有着非常重要的作用。但是如果钠摄入过多,又是高血压等慢性病的危险因素。钠离子还是中华人民共和国卫
生部在2011年发布的(iB28050-2011《食品安全国家标准预包装食品营养标签通则》中规定的4种核心营养
素之一,因此食品中钠的含量受到人们的广泛关注。食品中钠离子含量的测定对于保证人体健康有重要意义,
也是目前国内研究的热点问题,目前有多种方法实现了对钠离子的准确定量检测,包括色谐法、原子吸收光谱
法、滴定法等.各有优缺点。本文针对各种检验技术进行了详细的对比、对近年来食品中钠离子检测方法的研
究进行了综述
关键词:钠离子:温度滴定法;原子吸收光谱法:色谱法;电感耦合等离子体质谱法

ABSTRACT: Sodium is an important mineral in food, which can maintain the bodys normal osmotic pressure and
metabolism as well as can maintain acid-base balance in the body, so it 1s very important for human health. If the
intake om sodium is excessive, it will cause hypcrtension and other chronie discases Sodium is onc of the 4 kinds ol
core nutrients in (B 28050-2011 ationa/ food safer standard-(Eneral nutrition labels standard for pre-packaged
food published by the Ministry of Health of the PRC. Therefore, the content of sodium in foods gains widespread
concerns. Detcrmination o! sodium ion is important for human health, also bccomcs the research focus. Thcre are lots
of methods lor detection o[ sodium ion, and each method has advantages and disadvantages. T'his paper compared the
different analytical methods and reviewed the recent researches of analytical methods of sodium ion in food
