Abstract

Thermochemical reactions of tin, antimony, and lead iodination in a cavity of a small chamber electrode were studied. These reactions reduce the detection limits for analytes. It was shown that alkali and alkaline-earth metal iodides cannot be iodination agents. It was shown by spectrographic measurements that cadmium iodide mixed with carbon powder is the most efficient iodination agent. At the optimum conditions for analyte vaporization, the macrcomponents of the sample matrix (sodium, potassium, calcium, magnesium, aluminum, and iron) have almost no effect on the results of analysis. Based on the results obtained, a method was developed for determining tin, antimony, and lead in mineral stocks by atomic emission spectroscopy.
