Abstract: We have developed a new technique based on the rules of high-temperature processes in flame for the indirect determination of sulphur dioxid, sulphuric acid and phosphoric acid in natural samples by flame atomic absorption spectrometry (FAAS). The main point of the method is the difference in atomizaton of various inorganic salts of magnesium based on their thermal differences. In particular the magnesium perchlorate gives 10 times greater absorbance signal than the magnesium sulphate in the same concentration. The absorption of sulphur dioxide from air in hydrogen peroxide gives sulphuric acid, which can be determined by the previously mentioned method. The detection limit of the new method for sulphuric acid is 1.5•10-6 mol/L while the range of determination for is 3•10-6 – 4.1•10-5 mol/L. Since FAAS is one of the fastest analytical methods, our indirect FAAS acid determination is capable for serial analysis. With this new method we have determined the sulphuric acid content of the atmosphere of a battery recharging facility.
