利凡诺注射液的含量测定,一般参照部颁标准采用重量法。但此法检品用量多,测定费时。笔者根据利凡诺结构中芳伯胺基在盐酸酸性下与亚硝酸钠定量地完成重氮化反应这一原理,采用永停滴定法测定利凡诺的含量,结果 Ricardino injection content determination, the general reference to the ministerial standard weight method. But this method seized more dosage, measurement time-consuming. Based on the principle that the aromatic primary amine group in the rivanol structure is diazotized with sodium nitrite quantitatively under the acidity of hydrochloric acid, the content of rivanol is determined by the elution stop titration method. The result
