摘要
研究了在火焰原子吸收光谱法中阳离子型表面活性剂十二烷基三甲基氯化铵对钼的增感作用。在仪器工作最佳条件及合适的酸存在下，１０ｇ·Ｌ－１十二烷基三甲基氯化铵可使钼的吸光度增感４４．５％，且能消除多种共存元素的干扰。建立了钼的质量分数大于０．
The enhancement effectiveness of cationic surfactant,DTAC,for analytic sensitivity on determination of molybdenum in flame atomic absorption spectrometry is studied.The absorption can be enhanced by 44.5% and interference of coexisting elements can also be eliminated with 10gL-1dodecyltrimethylammonium chloride under the best condition of instrument and suitable acid existing.An ideal method is presented to determine molybdenum in alloy steels with molybdenum content over 0.29%. \=
