Abstract
A method of acid digestion is optimized for the simultaneous determination of five alkali elements in geological samples of different compositions and genesis by flame atomic emission spectrometry with multichannel spectrum registration. It provides an increase in the analytical signals and the expansion of the analytical range for each determined element. The accuracy and precision of the results are validated by the analysis of natural standard samples and by the method of standard additions. The application of the proposed method of the acid digestion of powder samples reduced the cost of analysis.
