Summary:A method for the determination of the content of Zn, Mg and Ca in Therapeutical Nutrients by flameless atomic absorption spectrometry is described. This elements were determined after microwave digestion of the samples. To establish optimum conditions for mineralization procedure, different parameters such as mass of the sample, amounts and ratios of used acids, times and power of microwave digestion were tested. The results showed that microwave digestion of samples allows to perform complete mineralization of the sample in short time and with no losses of the determined element.
