“…The technology has great natures, including low detection limit, wide linear range, less interference, high precision of analysis, rapid, multi-element simultaneous determination, and which is able to determine most of elements in the Periodic Table . Currently researches on tombarthite component in water samples are not many, some directly use the high sensitivity of inductively coupled plasma mass spectrometer for analysis [1], but some also use synergistic solvent extraction of water samples for processing and then use the mass spectrometer [2] to determine, and the foreign scholars determinethe transition and tombarthite metals in seawater by using time flight mass spectrometry of a flow injection with inductively coupled plasma [3]. Since mid-1980s, solid phase extraction is popular in foreign countries, and gradually replace the traditional liquid -liquid extraction technology, and currently has been widely used in environmental protection [4,5]. Shen Weimin and Qi Wenqi summarizes the pre-treatment methods for environmental samples, in which solid phase extraction applications are described in detail [6].…”
