    (1) Scope of application

    Suitable for solid waste and solid waste leachate in silver (Ag), arsenic (As), barium (Ba), beryllium (Bc), cadmium (Cd), cobalt (Co), chromium (Cr), copper (Cu), manganese (Mn), molybdenum (Mo), nickel (Ni), lead (Pb), antimony (Sb), smash (Se), thallium (TI), vanadium (V), zinc (Zn) and other 17 metal elements


    When the sampling volume of solid waste leachate is 25mmL, the detection limit of the above-mentioned 17 metal elements is 0.


    Table 5-37 Method detection limit and lower limit of determination for each element


    (2) Method principle

    After the solid waste leachate is pretreated by acid digestion, it is detected by an inductively coupled plasma mass spectrometer (Agilent 7700x), qualitatively based on the characteristic ions of the element, and quantified by the internal standard method.


    (3) Reagents and materials

    (1) Deionized water: first-grade pure water


    (2) Nitric acid : p(HNO 3 )=1.


    (3) Multi-element standard stock solution: p=1000mg/L


    (4) Multi-element standard solution: p=1.


    (5) Internal standard standard solution: p=1.


    (4) Instruments and equipment

    (1) Inductively coupled plasma mass spectrometer (ICP-MS): The mass range that can be scanned is 6 to 240 amu, and the slit width at 10% peak height should be 0.


    (2) Graphite digestion instrument: SCP DigiPREP MS graphite digestion instrument


    (3) Microwave digestion device: with programmable power setting function, the power of the microwave digestion instrument is above 1200W, and it is equipped with a microwave digestion tank of PTFE or the same material


    (4) Other equipment: balance (accurate to 0.


    (5) Sample preparation The samples are in accordance with "Solid Waste Leaching Toxicity Leaching Method Sulfuric Acid Nitric Acid Method" (HJ/T299), "Solid Waste Leaching Toxicity Leaching Method Acetic Acid Buffer Solution Method" (HJ/T300), "Solid Waste Leaching Toxicity Leaching Method Level" "Oscillation Method" (HJ557) for preparation
