Abstract A sample preparation method has been developed that provides a nitric acid-hydrogen peroxide digestion of plant tissue when it is heated internally by the oscillating electromagnetic field generated in a microwave oven. The total elemental concentration for barium, calcium, magnesium, manganese, phosphorus, potassium, sodium, sulfur, and zinc can be determined by inductively coupled argon plasma emission spectroscopy after sample preparation in a microwave oven. The method is rapid and provides quantitative results that agree with certified values for 4 National Bureau of Standards Standard Reference Materials: 1570 Spinach, 1572 Citrus Leaves, 1573 Tomato Leaves, and 1575 Pine Needles.

Abstract Nine elements (B, Ca, Cu, Fe, Mg, Mn, P, K, and Zn) were determined in 34 Magruder fertilizer standards by inductively coupled argon plasma (ICAP) emission spectroscopy. The total elemental concentrations found for each of the 9 elements compared favorably with known concentrations. Seventeen of the fertilizer samples were also extracted with ammonium citrate, and the phosphorus in the extract was determined by ICAP emission spectroscopy with good results compared with the known Magruder concentration for available phosphate. Concentrations of other elements (Al, Ba, Cd, Co, Cr, Na, Ni, Pb, Si, and Sr) were also obtained but were not verified.

Abstract Determination of Mg, re, and Zn by inductively coupled plasma emission spectroscopy (ICP) and by the official flame atomic absorption spectrophotometric (FAA) method were compared. Samples were acid digests of commercial fertilizers. Neither matrix effects nor spectral interferences were encountered in the ICP analyses. Linear regression shows that the slopes obtained by plotting ICP results vs FAA results for each element differ from unity by less than 5%.
