| Abstract: | 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%. |
