代赭石应用历史悠久。但代赭石生用还是煅用,从古到今无一定论。为此,作者对代赭石炮制前后含砷量的变化进行了探讨。结果表明,煅代赭石中砷的含量大大减少,并且煅后代赭石质地松脆,易于有效成分的溶出。故建议应将砷含量作为摄制代赭石的质量标准。 Daishishi has a long history of application. However, on behalf of the meteorite used or calcined, there is no certainty from ancient to modern times. To this end, the author discussed the change of arsenic content before and after the processing of Daishi stone. The results showed that the content of arsenic in calcined meteorite was greatly reduced, and the calcareous texture of the calcined offspring was crunchy and it was easy to dissolve the active ingredient. Therefore, it is recommended that the arsenic content should be used as the quality standard for the production of substitute gangue.
