原子吸收分光光度法测定燕麦中微量元素

Atomic absorption spectrometry determination of trace element in the oat

以中国湖北、甘肃和河北燕麦为样品,用浓硝酸过氧化氢处理样品,原子吸收火焰法测定燕麦中钙、镁、铜、锌4种微量元素.所测定的燕麦中含有丰富的人体必需的微量元素,采用此方法回收率在98.6%～100.4%,结果表明该方法实验数据可靠,结果可信.

The oat to Hubei,Gansu and Hebei for samples,to process samples of oat with HNO3-H2O2,atomic absorption flame method to determine the oat of the four trace elements like Ca,Mg,Cu,Zn. The determination of the oatmeal contains rich essential trace elements,and restricted by this method recovery rate is 98. 6% ~ 100. 4% and the results is reliable believable.
