Notes:
The Air-acetylene Flame Atomic Absorption Spectrometry (FAAS) was used to measureSr content in Mg-Sr Alloys. The experiment conditions including acetylene flow rate, measurementheight, flame wavelength were studied and the disturbing factors were discussed. It was found that, asdissolution agent of alloys and LaCl3 as the deionization agent and flame wavelength being 460.7nm,the detection limits is 1.16mg/L and the relative standard deviations is less than 0.3% and the recoveryrates of Sr is more than 95%. The advantages of this method were summarized as: high sensitivity andprecision, low chemistry disruption, good selectivity, good recurrence characteristics of themeasuring conditions. The method is suitable for the control analysis and sample-system analysis ofdetermination Sr content in the Mg-Sr Master Alloys
