傅里叶变换红外分光光度法鉴别白矾及枯矾的实验研究

目的: 比较白矾和枯矾红外光谱特征,寻求红外光谱是否对白矾及枯矾有鉴别意义。 方法: 运用红外光谱及二阶导数谱,对不同产地白矾及枯矾进行分析。 结果: 白矾及枯矾红外光谱图有明显差异。 结论: 红外光谱技术可以对白矾及枯矾进行直接、快速、有效分析,为白矾及枯矾鉴别和质量控制提供可靠依据。

Objective: To explore if the IR spectra analysis is useful for learning the Alumen,compare with the character of IR spectrometry alumen and its processed products. Methods: The alumen and its processed products from different producing area were studied by IR spectral and the secondary derivative IR spectra. Results: There were obvious differences of the IR spectrometry between alumen and its processed products. Conclusion: IR technology provides a method for the quality control and discrimination of alumen and its processed products.
