摘要
对GB/T 6730.59-2005铁矿石锰含量的测定火焰原子吸收光谱法标准中的试料分解方式、试料量、原子吸收光谱仪的主要分析条件火焰类型及测定分段稀释比例、匹配的校准曲线溶液配制进行了讨论,指出了原标准执行中这些条件的一些问题,建议修订此标准,建立切实有效、方便可行的标准,适合广大实验室的应用。
Several requirements in Iron ores-Determination of manganese content-Flame atomic absorption spectrometric method（GB/T 6730.59-2005） were discussed, including specimen decomposition method, specimen weight, and main analysis conditions of atomic absorption spectrometer（flame type, sectionalized dilution rate, preparation of calibration solution）. Some problems revealed while executing the original method, in the way, method optimization was suggested, in order to produce a more effective, more convenient and more feasible method, which could be applied among laboratories.
