摘要
研究了在火焰原子吸收光谱法中三乙醇胺及十二烷基三甲基氯化铵对钼的增感作用。在仪器最佳工作条件及合适的酸存在下，60g／L三乙醇胺及16g/L十二烷基三甲基氯化铵可使钼的吸光度增感70．4％，且能消除多种共存元素的干扰。建立了合金钢中大于0．05％钼的测定方法。
It is reported that in the presence of an appropriate amount of triethanolamine(TEA) anddodecyltrimethylam-monium chloride (DTAC ), the sensitivity for the flame atomic absorption spectrometricdetermination of molybdenum is remarkably enhanced. The absorption can be enhanced by 70. 4% andthe interference of some coexisting elements can also be eliminated with 60 g/L TEA and 16 g/L DTACunder the best condition of instrument and acid existing. An ideal method is presented to determinemolybdenum in alloy steels with molyddenum quantity over 0.05%.
