Abstract

This paper presents some recent applications of Flame Atomic Absorption Spectrometry (FAAS) to different matrices and samples. The time window selected was from 2006 up to March, 2011, and several aspects related to food, biological fluids, environmental, and technological samples analyses were reported and discussed. In addition, the chemometrics application for FAAS methods development was also taken into account, as well as the use of metal tube atomizers in air/acetylene flame. Preconcentration methods coupled to FAAS were discussed, and several approaches related to speciation, flotation, ionic liquids, among others were discussed. This paper can be interesting for researchers and FAAS users in order to see the state of the art of this technique.

Highlights

Flame Atomic Absorption Spectrometry (FAAS) is one of the most successfully implemented analytical techniques
It should be pointed out that external calibration was effective for reaching proper accuracy [44]
The developed system could adjust the viscosity of serum samples, perform Cu determination in serum, and preconcentrate Cu in urine followed by its subsequent elution and determination

Summary

Introduction

Flame Atomic Absorption Spectrometry (FAAS) is one of the most successfully implemented analytical techniques. Its main characteristics are the versatility and low cost (acquisition and operation). Several AAS approaches are presented in the literature, such as those using metal tube atomizers, hydride generation, and preconcentration procedures. The main objective of this paper is to present Flame and Flame Furnace AAS applications related to food analysis, fuels, biological fluids, environmental samples and technological materials, chemometrics, and preconcentration step. Several papers were organized from 2006 to March, 2011, and its main characteristics are reported and discussed.
