Spectrophotometry, atomic - Open Access .click

Medicine, Science and the Law, 1973
Historically flame emission spectroscopy was developed first. Routine analysis showed the advantage of measuring absorption over emission for many metals. Instrumentation requirements are:— 1. Pressure regulators and flowmeters with the sources of gases; 2. Atomizer; 3. Burner; 4. Optical system; 5. Detector. In addition, an energy source, e.g.,

Atomic Absorption Spectrophotometry in Water Analysis

American Industrial Hygiene Association Journal, 1969
Abstract The application of AAS to the analysis of major and certain trace elements in fresh and natural waters has been discussed. Sodium, potassium, calcium and magnesium were determined either directly or after dilution with deionized water. Pre-concentration of trace elements by simple evaporation was found to be satisfactory and compared favorably

Determination of molybdenum by atomic-absorption spectrophotometry

Talanta, 1972
A new procedure is described for precise estimation of molybdenum by atomic-absorption spectrophotometry using an airacetylene flame. Phosphoric acid was found to be effective in suppressing interference by Fe(III), Al, Sb(III), Ca, Mg, Pb and Mn(II).

Determination of thallium by atomic absorption spectrophotometry

Fresenius' Zeitschrift für analytische Chemie, 1966
The determination of thallium by atomic-absorption Spectrophotometry is described. Many substances interfere with the direct analysis of thallium under the conditions chosen. However, these interferences can be overcome by adding a lithium, potassium, or sodium buffer (5000 ppm). In this way the deviations caused by foreign substances can be reduced to
