Determination of Zinc Content in Zinc Gluconate Oral Solution by Flame Atomic Absorption Spectrometry
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".
