| Abstract: | The determination of potassium in mixed fertilizer was investigated by flame atomic absorption spectrometry in which the next sensitive spectrum line K 404. 4 run was to be taken as analytical spectrum line. The linear range of the method is 0 -208 mg/L, the regression equation is A =0.0026c -0.0100, the correlative coefficient is 0. 9992, RSD is 2.4% -5.0% and the recovery is 95. 6% - 101. 3%. The test result of the method is basically identical with that of potassium tetraphenylborate method. The method is simple and rapid. |
