蛋白银有强蛋白银与弱蛋白银二种,这二种药品的含量测定法是相同的。在中国药典中规定的方法,是将样品先炽灼灰化后,再以硝酸溶解,然后以硫酸铁铵作指示剂,以硫代氰酸铵来滴定。这个方法在操作时,手续较为麻烦,费时亦较多,而且在某些小型的化验机构或医院药局中因没有灰化炉,进行亦有相当困难。我们试验结果,认为蛋白银的含量测定,可以不经
Silver protein silver has a strong protein silver and silver two kinds of weak, these two drugs content determination method is the same. The method specified in the Chinese Pharmacopoeia is to first incinerate the sample ashing followed by dissolution with nitric acid followed by titration with ammonium thiocyanate to give an indicator of ammonium ferric sulfate. This method is more troublesome and time-consuming to operate, and it is also quite difficult to carry out it in some small laboratories or hospitals because there is no ash furnace. Our test results, that the determination of protein content of silver, may not
