【Abstract】 A method for determination of trace manganese in gasoline by atomic absorption spectroscopy was studied. The organic samples were dissolved in methyl tricaprylammoniun chloride (MTCAC) MIBK solution, and the standard solution was prepared by dissolving MnCl 2 in Br water MTCAC MIBK solution. The samples were atomized by the poor flame of air/acetylene gas, thus it needn’t to transfer the samples into another phase through ashing and extraction, so it’s simple and quick. The recovery is 94.9%108.8%, and the RSD is 1.6%.更多还原
