| Abstract: | A method for the determination of major and minor elements in soils by X ray energy spectrometry with pressed powder pellet sample preparation method was developed. Standard reference soil samples and synthetic standard samples were used to study the matrix effect and its correction. The method has been applied to the determination of Si, K, Ca, Ti, Mn, Fe and Sr in standard soil samples. The results are in agreement with certified values with precision of <3% RSD ( n =5). |
