测定氨基磺酸的标准方法的探讨

A Discussion on the Standard Methods For Determing Sulfaminie Acid

为解决环已基氨基磺酸钠的主要原料──高纯度氨基磺酸（NH2SO3H）含量测定的准确性，对几种氨基磺酸含量和硫酸盐（SO4）含量的测试方法进行了实验对比和理论探讨，证实了高纯度氨基磺酸含量的测试应采用HG／T2527－93规定的亚硝酸钠滴定法，并推荐采用总酸量法为硫酸盐（SO4）含量的测试方法。

In order to accurately measure the density of highly pure sulfaminie acid which is the main meterial of cyclohexylsulfaminic acid sodiumsalt, we compared serveral measuring methods ofr determing the density of sulfaminic acid and sulfate by means of erperiments and thoretical exploration, and confirmed the sodium notrite method stipulated in HG/12527 - 93 is a reliable one. We also recommend total - acid measuring method for measuring the density of sulftite.
