植物中氟含量的测定在地氟病的防治研究中,具有重要的意义,特别是燃煤污染植物食品的病区出现后,对植物氟的测定更加广泛。但植物中微量氟的分析方法,国内外报道较少,而且对低氟含量样品的测定,所得结果误差较大。因此,建立 Determination of fluorine in plants in the prevention and treatment of endemic fluorosis is of great significance, especially in coal-contaminated plant food ward appears, the determination of plant fluoride is more extensive. However, the analysis method of trace fluorine in plants is less reported at home and abroad, and the determination of low-fluorine content samples results in a large error. Therefore, established
