| Abstract: | A method for the direct determination of copper and manganese in feed additive(premix) by flame atomic absorption spectrometry with secondary sensitive wavelength was developed. This method can greatly decrease the analytical errors caused by small amount of samples or great dilution multiple, so its accuracy is better than normal atomic absorption spectrometry using sensitive line when determining Cu-rich and Mn-rich feed additive samples. It was found that the method is simple, rapid, accurate and free from the interference of coexistent ions. It has been widely applied to the determination of feed additive samples with satisfactory results. |
