原子吸收法测钼有不少报道。David首先发表文章指出,铁、锰、镁、钙和锶干扰钼的原子吸收测定,而钙和锶的干扰尤为严重。他用氯化铝作干扰抑制剂。1966年 Mostyn 等人认为用2%氯化铵作释放剂效果比用氯化铝好。1975年Nall 用空气—乙炔焰测钢中钼时也是用氯化铵作释放剂。本工作采用2%氯化铵水溶液作释放剂,消除了10,000 ppm 铁及100ppm 锰、铜、钙、镁和锶的干扰,用直接火焰原子吸收法测定了六种合金钢中少量钼,获得了满意结果。
There are many reports of atomic absorption spectrometry molybdenum. David first published an article stating that iron, manganese, magnesium, calcium and strontium interfere with the atomic absorption spectrometry of molybdenum, with the interference of calcium and strontium being particularly serious. He used aluminum chloride as an interference inhibitor. Mostyn et al. In 1966 considered the use of 2% ammonium chloride as a release agent rather than aluminum chloride. 1975 Nall with air - acetylene flame test of molybdenum steel is also used as a release agent of ammonium chloride. In this work, 2% ammonium chloride aqueous solution was used as a releasing agent to eliminate the interference of 10,000 ppm iron and 100 ppm manganese, copper, calcium, magnesium and strontium. A small amount of molybdenum in six alloy steels was determined by direct flame atomic absorption spectrometry. Satisfactory result.
