摘要：

“火焰原子吸收光谱”是本科生仪器分析实验教学中的重要实验之一。原子吸收光谱用于实际样品中某一特定元素的定量测定，具有测定准确度高、精密度高和选择性好等优点。葡萄糖酸锌口服液是生活中常见的口服补锌类非处方药，通过本科生自主实验，建立火焰原子吸收实验方法，测定葡萄糖酸锌口服液中锌含量，方法简便、易于操作。通过该自主实验，培养学生利用课堂所学理论知识解决实际问题的能力，实现“学以致用，用以促学”的育人目标。

Abstract:

Flame atomic absorption spectrometry (FAAS) is an important experiment in instrumental analysis laboratory teaching for undergraduates. Atomic absorption spectroscopy (AAS) is used to quantitatively determine a specific element in real samples, which has the advantages of high accuracy, precision, and selectivity. Zinc gluconate oral solution is a common over-the-counter zinc supplement in daily life. Through independent experiments of undergraduates, a simple and easy-to-operate FAAS method is established to determine the zinc content in zinc gluconate oral solution. This experiment aims to cultivate students' ability to apply theoretical knowledge learned in class to solve practical problems, and achieve the educational goal of "learning for application, and application to promote learning".

Key words: Independent experiment, Atomic absorption spectrometry, Zinc content
