采用热重(TG)技术、热质联用(TG-MS)技术、红外光谱技术(FTIR)和扫描电镜(SEM)-能谱仪(EDS)联用技术探讨炉甘石热解特性,对炉甘石热解前后相关元素含量、整体形态、官能团及挥发分等变化进行定性、定量研究,发现200~360,580~750℃为炉甘石煅制过程中药效成分变化的2个敏感温度区间,200~360℃为ZnCO3,Zn(OH)2,ZnCO3-2Zn(OH)2-H2O热失重,580~750℃为CaCO3热失重。化学反应动力学研究结果表明,具有良好的线性关系。该试验融汇物理化学及中药炮制学的相关方法及理论,阐释炉甘石煅制炮制工艺及机制,为其他中药炮制的现代研究提供一个很好的范例。
The pyrolysis characteristics of calamine were explored by the combination of TG, TG-MS, FTIR and EDS (EDS) The results showed that 200 ~ 360,580 ~ 750 ℃ were the sensitive temperature range of the change of the active ingredient in the coking process of calamine, and the change of the content, the overall shape, the functional group and the volatile content of the relevant elements before and after pyrolysis of calamine, , The weight loss of ZnCO3, Zn (OH) 2 and ZnCO3-2Zn (OH) 2-H2O at 200-360 ℃ and the weight loss of CaCO3 at 580-750 ℃. The results of chemical reaction kinetics show that there is a good linear relationship. This experiment integrates the related methods and theories of physicochemical and traditional Chinese medicine processing to explain the processing technology and mechanism of calamine calcination and provides a good example for the modern research of other traditional Chinese medicine processing.
