摘　　要：锡是人类最广泛使用的金属之一,随着工业的发展,农药和染料的副产品排放污染土壤,以及喷洒的有机锡农药在作物和土壤中残留,这将导致土壤中的锡含量超标。相比较X射线荧光光谱分析仪法、火焰原子吸收光谱法、石墨炉原子吸收光谱法、原子荧光光谱法、电感耦合等离子体发射光谱法,电感耦合等离子体质谱法检测土壤中锡具有稳定性好,重复性高,抗干扰能力强,灵敏度高,检出限低,仪器效率高等优点,满足土壤中锡含量的准确定量的条件。Tin is one of the most widely used metals. With the development of industry, the by-products of pesticides and dyes pollute the soil, and the organotin pesticide residues in crops and soil, which will lead to excessive tin content in the soil. Compared with X-ray fluorescence spectrometry, flame atomic absorption spectrometry, graphite furnace atomic absorption spectrometry, atomic fluorescence spectrometry and inductively coupled plasma atomic emission spectrometry, inductively coupled plasma mass spectrometry has the advantages of good stability, high repeatability, strong anti-interference ability, high sensitivity, low detection limit and high instrument efficiency, which can meet the requirements of soil quality The conditions for accurate quantitative determination of tin content in iron ore were studied.
