采用盐酸溶解样品,火焰原子吸收光谱法测定摩擦材料中的铁,该方法操作简便、快速、准确。加标回收率为96%～101.5%,相对标准偏差为1.4%。 Hydrochloric acid was used to dissolve the sample and the flame atomic absorption spectrometry was used to determine the iron in the friction material. The method was simple, rapid and accurate. The spiked recoveries ranged from 96% to 101.5% with relative standard deviations of 1.4%.
