Abstract：Four digestion methods were used for the decomposition of plant samples. The contents of Al, B, Ba, Ca, Cu, Fe, K, La, Mg, Mn, Na, P, Pb, Sr, Ti and Zn in the two Standard Reference Materials 1573a (Tomato Leaves) and 1575(Pine Needles) were determined by using ICP-AES and the determined values were compared with the certified ones. It was demonstrated that hydrofluoric acid is of vital importance in the decomposition of plant samples, because it can remove silicious materials from the matrix. Appropriate selection of digestion methods can improve greatly the accuracy of elemental quantification in plant samples.
