Abstract
ObjectiveTo establish the methods of titrimetric determination of cinnabar (HgS) content in baoying powders.MethodsTo make the corresponding determination adopted the chemical titration with the digestants of sulphuric acid and potassium nitrate, the titration solution of ammonium rhodanate. At the same time, to make interrelated experiment such as dried in the shade test, replicate test, average recovery test and so on.Results The sampling amount was 1.2g as there was no significant difference with shorter time of digestion, less consumption of titration solution compared with the sampling amount of 2.4g and 4.8g. Under the sampling amount of 1.2g, the cinnabar(HgS) content in baoying powders had better repeatability ofRSD=0.58%(n=6) with the average recovery of 98.96%, RSD=0.55%.Conclusion Titrimetric determination of cinnabar(HgS) content in baoying powders has the characteristic of simple operation, reliable, accurate and so on, could be used on quality control of this kind of preparation.关键词
