摘要
用盐酸副玫瑰苯胺法比色测定自然铜中SO_2含量,并抽样测定药房中锻后样品中的SO_2量,制定出质量指标,筛选出最佳炮制条件,提出回收SO_2变害为益的有效方法。
This paper reports the colorimetic determination of total SO_2 in Zirantong by the method of rosaniline hydrochlorid. Samper of processed Zirantong from the pharmacy have been analyzed and the quality sperifications established. Optimum londitions for processing have been chosen and a proceduce has been proposed for the sebovery of the poisonous matter SO_2 which is then transfermed into a beneficial material.
