本文究了干法灰化样品,以直流粉末法对茶叶等植物体中稀土元素进行光谱测定。工作中以无机盐制配“人工模拟基体”,用其配制标准试样,对茶叶及铁花所作的分析其精密度与准确度都得到较满意的结果。 In this paper, the dry ashing samples were studied, and the DC powder method was used to determine the rare earth elements in tea and other plants. Work with inorganic salt system with “artificial simulated matrix”, with its preparation of standard samples, the analysis of tea and iron flower its precision and accuracy are more satisfactory results.
