Abstract

Two methods are presented for the quantitative determination of total iron and manganese in soils. The first necessitates the preparation of a calibration curve and is applicable only to soils having similar properties. In this method known increments of Fe₂O₃ and/or MnO₂ are added to the original soil, and X-ray fluorescence intensities are obtained. Analysis of an unknown then utilizes the resulting equation which expresses the relation between intensity and concentration. A second method, here called the two-point method, does not require a calibration curve and is valid for a wider range of samples. A sample is analyzed for either iron or manganese, and X-ray fluorescence intensities are obtained; then a known amount of the element is added to the sample and intensities are again measured. A suitable equation utilizing the two intensities for the determination of the element in the original sample is presented. Data are included to indicate that this method is satisfactory and accurate.
