摘要
采用燃烧碘量法测定了矿物药硫黄及其炮制品在酸性(人工胃液)、碱性和中性介质中的溶出率,结果表明炮制后的硫黄溶出率均高于天然硫黄的溶出率。文章提出的燃烧碘量法测定溶液中微量硫方法,最小检出限为6.5μg,方法的回收率为97%~99%,RSD<0.6%。
Dissolved ratio of mineral drugs sulphur and preparation drugs in acidmedium and alkli medium and neutral mJium is determined by the method ofcombustion iodometry.Testing results showed dissolved ratio of preparation drugs morethan nature sulphur,Detectable limit of this method is 6. 5 μg. Recovery ratio of thismethod is 97%~99%. The relative standard deviation(RSD)is less 0.6%. The methodof combustion iodometrv in the thesis is sensitive,accurate,usable.
