Objective: To establish an indirect atomic absorption spectrometry method for determination content of mangifer in Ermu Ningsou Wan. Method: Based on the mangifer can be quantitatively generate brown precipitation with Sr2+ in alkaline environment

the content of mangifer in samples was determined indirectly by atomic absorption spectrometry. The effects of temperature

reaction time

pH value and amount of strontium chloride were studied. Result: The conditions of precipitate reaction were chosen as follow:1.00 mL strontium chloride solutions (1.395 g·L-1)

40℃

pH 9.0

and react 20 minutes. Meanwhile

the linear range was 2.11 to 59.95 mg·L-1 and the detection limit was 0.25 mg·L-1. The recovery rate was 96.74%±1.07%. This method performed good stability

precision and repeatability. Conclusion: The proposed method is easy to control and allows the determination of mangifer in a wide range. The results for the analysis are satisfactory.
