【摘要】 将石墨乳加盐酸煮沸使石墨微粒凝析,铁溶解,采用空气-乙炔火焰原子吸收法测定滤液中铁的含量。建立了优化的仪器测定条件,并对可能存在的元素进行了干扰实验。该方法的回收率为98.0%～100.5%,相对标准偏差为1.7%～2.5%。方法简便、灵敏、准确,有实用价值。更多还原

【Abstract】 Graphite emulsion was added to hydrochloric acid solution and boiled to make graphite particulates condensate,and iron was dissolved.The content of iron in filtrate was determined by air-acetylene flame atomic absorption spectrometry.The optimum determination conditions were optimized and the test for the interferential elements that probably exist was conducted.The recovery rate was 98.%~100.5%.The relative standard deviation was 1.7%~2.5%.The proposed method was easy,rapid and sensitive.更多还原
