Quantitative analysis of metals in soil using X-ray fluorescence

Using energy dispersive X-ray fluorescence analysis with an X-ray tube filtered with Ti, it was possible to determine the concentration at ppm level of several elements (K, Ca, Ti, Mn, Fe, Cu, Zn, Ga, Br, Rb, Sr, Zr, Y and Pb) in soil treated with organic compounds of urban garbage. It was possible to observe a significant increase in the contents of K, Ca, Zn, Rb, Sr, Zr and Pb in the soil treated in comparison with the soil control.
