Scope

This standard specifies the wavelength dispersive X-ray fluorescence spectrometry method for the determination of 16 inorganic elements and 7 oxides in solid waste such as sludge, contaminated soil, fly ash, soot, tailings waste rock and smelting slag. This standard is applicable to the determination of 16 inorganic elements and 7 oxides in solid waste such as sludge, contaminated soil, fly ash, soot, tailings waste rock and smelting slag, including arsenic (As), barium (Ba), Chlorine (Cl), cobalt (Co), chromium (Cr), copper (Cu), manganese (Mn), nickel (Ni), phosphorus (P), lead (Pb), sulfur (S), strontium (Sr), Titanium (Ti), vanadium (V), zinc (Zn), zirconium (Zr), silicon dioxide (SiO2), aluminum oxide (Al2O3), iron oxide (Fe2O3), potassium oxide (K2O), oxide Sodium (Na2O), calcium oxide (CaO), magnesium oxide (MgO). This standard uses the molten glass sheet method or the powder tableting method to prepare solid waste samples. The molten glass sheet method is suitable for the preparation of solid waste samples such as sludge, contaminated soil, fly ash, soot, tailings waste rock, smelting slag, etc., but is not suitable for determining the content of chlorine (Cl) elements; the powder tableting method Suitable for preparation of solid waste samples such as sludge, contaminated soil, fly ash, smoke and so on. The method detection limit of 15 inorganic elements prepared and determined by the molten glass method is 5 mg/kg~70 mg/kg, and the lower limit of determination is 20 mg/kg~280 mg/kg; the method detection limit of 7 oxides It is 0.01% to 0.03%, and the lower limit of determination is 0.04% to 0.12%.
