Flame emission, atomic absorption, and atomic fluorescence spectrometry

Abstract

This is the first biennial review to be prepared by the present authors, the previous three having been written by Professors James D. Winefordner of the University of Florida and Thomas J. Vickers of Florida State University. We all owe a deep debt of gratitude to both these men for their efforts on behalf of the analytical community.The title of this review section has been changed from "Flame Spectrometry" to the present one. This change re-

Enhancement of atomic absorption sensitivity for cadmium, manganese, nickel, and silver and determination of submicrogram quantities of cadmium and nickel in environmental samples

“…Extraction data for a 1 jug/mL silver solution was obtained. Four solvents and three complexing agents were used to extract silver, for a total of 12 <0.1-4.5 ng/mL 0.1-80 ng/mL a Three replicates for each sample, % RSD = 10. 6 Range for 51 samples taken from Kentucky Lake, Barkley Lake, Cumberland River, and Tennessee River at selected sites over an 18-month period. studied were n-butyl acetate, 3-heptanone, 2,4-pentanedione, and MIBK.…”

High solids sample introduction for flame atomic absorption analysis

“…The use of hydrochloric acid and zinc granules for hydride formation has been replaced for the greater part by the use of hydrochloric acid and NaBH4 because of the cleanliness of operation and relative technical ease. Coupling NaBH4 hydride generation and an argonhydrogen flame has been well-documented (2)(3)(4). Several papers have dealt with limited potential interference (3,5).…”

“…Although less sensitive than flameless atomizers, conventional burner-nebulizers have proven to be generally more convenient to operate, lower in cost, capable of introducing a larger number of samples per unit time into the absorption cell, and less susceptible to interferences (4,5). These advantages have established the continued use of the capillary pneumatic nebulizer as a principal sample introduction device for analytical atomic spectroscopy.…”

Overcoming Matrix Effects in a Complex Sample: Analysis of Multiple Elements in Multivitamins by Atomic Absorption Spectroscopy

“…Atomic absorption spectroscopy (AAS) is among the most valuable tools in analytical chemistry , . AAS is capable of analyzing samples for the presence of elements, particularly metals.…”
