Abstract
A 2-step digestion procedure using HNO3 and H2O2/UV irradiation is described. The samples [humus, foliage of birch, spruce and pine] are predigested with NHO3, succeeded by digestion in H2O2 under UV irradiation. The maximum temperature is 150.degree. C. The digestion is performed without sample transfer during oxidation. The analytical data obtained by the new digestion method do not deviate from those obtained by HCO4 digestion. Macronutrient elements [P, S, Na, K, Mg, Ca, Mn, Fe and Al] were measured.Keywords
