Standard methods for the examination of water and wastewater (543.3 APHA 24th ed. Ref. Treatises&monographs FL2)
This method is designed to determine trace metals and metalloids in surface, ground, and drinking waters via inductively coupled plasma-mass spectrometry (ICP-MS). Although best suited for ambient or pristine freshwater matrices, this method can also be used to analyze wastewater, soils, sediments, sludge, and biological samples after appropriate digestion followed by dilution and cleanup to reduce matrix effects to a manageable level. Various cleanup techniques are available to reduce matrix interferences and concentrate the analytes of interest...
