Scope

This Standard specifies the wavelength dispersive X-ray fluorescence spectrometry method for
the determination of 25 inorganic elements and 7 oxides in soil and sediment.
This Standard is application to the determination of 25 inorganic elements and 7 oxides in
soil and sediment; including Arsenic (As), Barium (Ba), Bromine (Br), Cerium (Ce), Chlorine
(Cl), Cobalt (Co), Chromium (Cr), Copper (Cu), Gallium (Ga), Hafnium (Hf), Lanthanum (La),
Manganese (Mn), Nickel (Ni), Phosphorus (P), Lead (Pb), Rubidium (Rb), Sulfur (S),
Scandium (Sc), Strontium (Sr), Thorium (Th), Titanium (Ti), Vanadium (V), Yttrium (Y), Zinc
(Zn), Zirconium (Zr), Silicon Dioxide (SiO2), Aluminum Oxide (Al2O3), Ferric Oxide (Fe2O3),
Potassium Oxide (K2O), Sodium Oxide (Na2O), Calcium Oxide (CaO), Magnesium Oxide
(MgO).
The detection limit of this method for 22 inorganic elements is 1.0mg/kg~50.0mg/kg; the lower
limit for determination is 3.0mg/kg~150mg/kg. The detection limit for 7 oxides is
0.05%~0.27%; the determination lower limit is 0.15%~0.81%. See Appendix A for details.
