HJ 1315-2023 Determination of total amounts of 19 metal elements in soil and sediments by inductively coupled plasma mass spectrometry (English Version)
This standard specifies the inductively coupled plasma mass spectrometry method for determining the total amount of 19 metal elements in soil and sediments. This standard applies to silver (Ag), arsenic (As), barium (Ba), beryllium (Be), bismuth (Bi), cadmium (Cd), chromium (Cr), cobalt (Co), copper ( Cu), lithium (Li), manganese (Mn), molybdenum (Mo), nickel (Ni), antimony (Sb), strontium (Sr), lead (Pb), thallium (Tl), vanadium (V) and zinc ( Zn) Determination of a total of 19 metal elements. When the sampling volume is 0.1 g and the fixed volume after digestion is 50 ml, the method detection limit of 19 metal elements is 0.02 mg/kg~5 mg/kg, and the lower determination limit is 0.08 mg/kg~20 mg/kg. See Appendix A for details.
