| Abstract: | It is reported that in the presence of anappropriate amount of triethanol amine (TEA) and dodecyltrimethyl-ammonium chloride(DTAC), the sensitivity for the FAAS determination of molybdenum and the ability toeliminate interference are remarkably enhanced. Its mechanism is to reduce the surfacetension of solution, to enhance the efficiency of nebulization, to generate glue group ofchemical combination and to concentrate molybdenum by surfactant. |
