研究在 Tween-20增溶下,双硫腙水相直接分光光度法测定中成药冰硼散、三七片中的锌、汞含量。确定了实验条件。同时研究了干法、湿法及微波法消解对样品的处理效果。为中成药的前处理方法提供了一定依据。
In the study of Tween-20 solubilization, dithizone aqueous phase direct spectrophotometric determination of zinc and mercury content in Chinese medicines Bingbosan and Sanqi tablets. The experimental conditions were determined. At the same time, the effects of dry, wet and microwave digestion on the sample were studied. It provides a certain basis for the pretreatment method of proprietary Chinese medicines.
