摘要
目的:探讨新方法用于朱砂质量控制的可能性,以保证朱砂的安全使用。方法:应用激光Raman光谱仪分别对纯品HgS,HgO及可溶性HgCl2和朱砂样品粉末进行光谱扫描,通过比较朱砂样品和对照品Raman光谱形状和特征峰,对朱砂样品进行无损分析鉴定。结果:HgS,HgO和HgCl2的激光Raman光谱曲线形状互有差别,分别有明显的特征峰,而质量达标的朱砂样品Raman光谱及特征峰均与纯品HgS相同,并与HgS含量测定结果相符。结论:用Raman光谱分析可对朱砂直接进行无创鉴别,且快速、准确,可用于朱砂的质量控制,建议作为朱砂新的质量标准方法之一。
Objective： To develop a new quality control method for cinnabar, in order to ensure the safety application of cinnabar. Method： Three inorganic mercury compounds （HgS, HgO, and HgCl2） and cinnabar samples were analyzed by laser Raman spectroscopy. The cinnabar samples were identified by comparing the Raman band in the Raman spectrum with pure HgS. Result： Different Raman bands were observed among three inorganic mercury compounds. The Raman spectroscopic results indicated that cinnabar samples showed the same Raman band as pure HgS, consisting with the HgS contents by XRF analysis. Conclusion： The Raman spectroscopic method is simple, rapid, and reliable. It can be applied as an alternative quality control method for cinnabar.
