OKUMURA, Fabiano; CAVALHEIRO, Éder T. G.  and  NOBREGA, Joaquim A.. Simple flame photometric experiments to teach principles of atomic spectrometry in undergraduate analytical chemistry courses. Quím. Nova [online]. 2004, vol.27, n.5, pp.832-836. ISSN 0100-4042.

The purpose of this paper is the development of simple strategies to teach basic concepts of atomic spectrometry. Metals present in samples found in the daily lives of students are determined by flame atomic emission spectrometry (FAES). FAES is an accurate, precise, and inexpensive analytical method often used for determining sodium, potassium, lithium, and calcium. Historical aspects and their contextualization for students are also presented and experiments with samples that do not require pre-treatment are described.

Keywords : flame atomic emission photometry; education in analytical chemistry; instrumental analysis.
