摘　　要：研究了原子吸收法测定钼精矿中铁元素的影响因素,发现钼基体对铁的测定有影响,导致测定结果偏低,采用氨水沉淀铁的办法消除钼基体的影响因素,使测定结果的准确度、精密度均较好。The influecing factors of Fe content in molybdenum concentrates determined by atomic absorption spectrometry wers studied. It is found that molybdenum matrix influenced the determination result of Fe and caused the result number low. The influence of molybdenum matrix was removed by adding ammonia solution to precipitate Fe, so that accurate result was gotten.
