【Abstract】 An improved method of flame atomic absorption spectrometry (AAS) for the determination of molybdenum in soil was described. By the use of rich-flammable air-acetylene flame and in the presence of Triton X-100 and triethanolamine, the sensitivity and selectivity of the AAS determination were remarkably improved. The sensitivity was raised to an extent of 55%. The recoveries obtained by the analytical results of 6 soil samples were in the range of 91.2% to 103.7%.更多还原
