摘要
采用湿法消解原子荧光光度法对甲鱼肉中硒元素含量进行了分析测定. 该方法加标回收率为96.2%～103.0%, 相对标准偏差(RSD)为3.69%, 猪肉国家标准物质(GBW08552)的测定值与标准值相吻合. 结果表明: 甲鱼肉中硒元素的含量非常丰富, 硒含量是普通动物鲜肉中的1.2～9.4倍;是新鲜瓜果蔬菜的几十至几百倍. 本测定结果可为研制开发富硒甲鱼保健食品提供有价值的和可靠的科学依据.
The Se content in Trionyx triunguis was studied by atom fluorescence photometer with wet digestion. The recovery of the method is 96.2 %-103.0 %, relative standard deviation is 3.69 %, the determined value of national standard substance pork are agree with standard value; and the method is simple, convenient, fast with good accuracy and precision. The results showed that Se in Trionyx triunguis was very rich, more 1.2-9.4 than Se contant in animal meal, more ten to hundred then it in refresh vegetables and fruits. These results provide a useful scientific base for making and exploiting healtyful foods with Se trionyx triunguis.
