    Abstract:Objective To introduce a method for evaluation of the uncertainity of manganese in water by using atomic obsorption spectrometry and provide scientific basis for setting up of effective quality control. Methods The factors affecting the testing results were determined and the results were integrated. Results The uncertainty of the result of Mn in water tested by atomic absorption spectrometry is0.011mg/L. Conclusion The method for determining Mn from water by atomic absorption spectrometry is clearand adequate and without repeated procedure and omission.
