微米/纳米雄黄微粒的制备及粒度测定

A Study on Preparation and Diameter Determination of Realgar Granule of Micron or Nanometer Dimension

目的 制备不同大小的雄黄颗粒并测定其粒径。方法 采用水飞、气流粉碎、细珠研磨和微射流 4种方法制备不同粒径的雄黄颗粒 ,并用激光粒度测试仪进行测定。结果 制得 4种微米、纳米级的雄黄颗粒。结论 通过采用新的制剂方法 ,可以得到微米。

OBJECTIVE To prepare realgar granules of different dimensions and determine their diameters. METHOD Water refinement, air current grinding, and refined grinding were adopted and the diameter of the granules was determined with a laser particle size analyzer.RESULT Four kinds of realgar granules of micron or nanometer dimension were obtained.CONCLUSION The new methods can be adopted to obtain realgar granules of micron or nanometer dimension.
