ABSTRACT
The objective of this report was the evaluation and establisment of an appropriate digestion procedure for soluble coffee, in order to determine, by ICP-AES(inductively coupled plasma atomic emission spectrometry), the following elementsMg, Al, P, S, Ca, Mn, Fe, Na, K, Cr, Ni, Cu, Zn, As, Se, Cd, Sb, Pb and Hg. Six differents digestion procedures have been evaluated and classificated in three groups (I) focused microwave system, (II) conventional wet digestion and (III) pressure digestion system by teflon bombs. Quick and safe digestion of the samples, with decreasing of the reactives, have been obtained by one of the procedures using focused microwaves system
