X-ray emission spectroscopy has been applied to determination of zinc in a variety of plant
species. Data are presented to show the lack of consistency in the intensity of the zinc …

The use of X-ray fluorescence spectrometryfor the analysis of plant tissue is well
established. First introduced in 1958 by Brandt and Lazar (2) for the determination of …

A volume‐reduction technique is described for the X‐ray spectrographic analysis of the
micronutrient elements manganese, iron, and zinc in plant tissues. This simple technique is …

A method is presented for the determination of trace elements in plant materials. The
samples were composed of organic material, which was eliminated by wet ashing, large …

Copper and zinc were determined simultaneously in plant leaves by neutron-activation
analysis. After ashing the leaves, in the presence of copper and zinc carriers, with fuming …

Briquets of ground corn leaves were made using a cementing agent called Permount and
analyzed for zinc content by X‐ray spectrography. Briquets prepared in this way were …

Energy dispersive X‐ray fluorescence (EDXRF) has been shown to be an effective
technique for multielement analyses of plant tissues. Elements can be assayed above the …

X-ray emission spectrography in comparison with many analytical tools provides a
nondestructive means of determining elemental concentrations in plant materials with …

A semiquantitative method of X‐ray fluorescence spectrometry using a manual spectrometer
has been developed for the rapid determination of Mn, Fe, Ni, Cu, Zn, As, Br, Rb, Sr, Y, Zr …

Method Samples of plant material are dried at 70 C. in a forced hot-air oven for 48 hours and
ground in a Wiley mill to pass a 20-mesh stainless steel sieve as previously reported (5) …
