Fe、Ca及微量元素Cu、Zn、Mn和Mg是人体中重要的营养元素、具有重要的生理功能,参与机体的新陈代谢,对儿童的智商和健康都起着相当重要的作用。本文采用火焰原子吸收光谱法测定了1—6岁儿童头发中上述元素的含量。方法简便、快速、精密度好,灵敏度高。一、主要仪器和试剂硝酸、盐酸、丙酮均为分析纯;镧释放剂,含氧
Fe, Ca and trace elements Cu, Zn, Mn and Mg are important nutrients in the human body. They have important physiological functions and participate in body metabolism. They play a very important role in children’s IQ and health. In this paper, Flame Atomic Absorption Spectrometry was used to determine the above-mentioned elements in the hair of 1-6-year-old children. The method is simple, rapid, precise and sensitive. First, the main equipment and reagents nitric acid, hydrochloric acid, acetone were analytical grade; lanthanum release agent, containing oxygen
